FINITE ELEMENT MODELING AND OPTIMIZATION OF SHOT PEENING PROCESS FOR 2024 ALUMINUM ALLOY FOR IMPROVING FATIGUE LIFE

IJAERS/Vol. III/Issue III/April-June, 2014/01-03

Authors:Loukik Vitthalprasad Kulkarni, Prof. Dr. V.V. Kulkarni, Swapnil S. Kulkarni

ABSTRACT
Shot peening is a process which is used to improve the fatigue life of component. In this present era where we are dealing with low weight requirements which requires low weight alloys having low fatigue strength, shot peening is emerged as a solution for improving the fatigue life. But selection of wrong parameters will lead to reducing the fatigue life rather than improving it. Finite Element Modeling is used as an effective technique for prediction of residual stresses in shot peening process. FEM will lead to saving the cost, time and efforts related to shot peening experimentation. This paper is focused on review of Role of FEM in shot peening.

DIE CASTING DIE DESIGN FOR A HIGH VOLUME AUTOMOTIVE COMPONENT USING CAE TECHNIQUES FOR SIMULATION

IJAERS/Vol. III/Issue III/April-June, 2014/04-07

Authors:Vishwajeet Vijaykumar Nimbalkar, R.R. Ghorpade, Swapnil S. Kulkarni

ABSTRACT
The quality of a die cast product is determined to a great extent by the mechanism of cavity fill. The evolution of this process has received attention both in industry and literature. Because of its effect on the cost of a numerical simulation, the question of whether or not the filling stage takes place under isothermal conditions needs to be addressed. The proposed work would analyze the process of fill in die casting and presents relations that can be used to predict the conditions under which the quality of the product, in terms of defect-free process, can be greatly enhanced.
The squeeze dies casting process or the LPDC/ HPDC of molten non-ferrous metal (aluminium/ magnesium) is very attractive for producing near net shape components with an arbitrary complicated shape. It is particularly attractive for processing engine mounting brackets with high strength at desired elongation and hardness, since the porosity of dispersed defects under the action of the pressure is remarkably reduced during squeeze casting. Therefore, to develop suspension parts, such as the knuckle, arm, and structure parts to support the automobile engine, the squeeze casting process was developed with die design and process parameter control.

INVESTIGATING THROUGH CAE, THE FAVORABLE EFFECTS OF THE RESIDUAL COMPRESSIVE STRESSES DURING SHOT PEENING PROCESS

IJAERS/Vol. III/Issue III/April-June, 2014/20-22

Authors:Mukund Ramdas Kharde, Mahesh K. Gaikwad, Swapnil S. Kulkarni

ABSTRACT
Metals fail under tension loads and not under compressive loads. The failure crack will usually initiate at the part surface where tension stresses are highest and a stress riser exists (scratch, dent, machine mark, etc). Parts subjected to fatigue tend to fail early due to the prominence of these tensile stresses that are detrimental to the life of the components subjected to cyclic loads.
The problem for this work is to identify through the deployment of CAE the effective levels (values) of the shot peening parameters (factors) to be suit the popular material for such applications. E.g. - Aluminum.

ABSTRACT
Coiled compression spring in the automotive segment pose a challenge for high cycle fatigue loading exceeding millions of cycles. This application pursued for the work aims to determine the best design for spring over its design parameters. Finite element modeling would help to understand and specify the levels for the design parameters regarding the Wire Diameter, Pitch, Material and need for co-axial orientation of the spring. The analysis would indicate the prominence of the design parameter and its effect over the performance of the spring in terms of fatigue life. The work would be pursued to conclude with a proposal specifying the suitable values (levels) for the significant parameters identified for this study. References are drawn from the literature review as well as the industry.

COMPARATIVE ANALYTICAL STUDY OF RESPONSE OF BRACE STRUCTURAL SYSTEM WITH CONVENTIONAL LATERAL LOAD RESISTING SYSTEM USING TIME HISTORY METHOD

IJAERS/Vol. III/Issue III/April-June, 2014/34-39

Authors:Ashik S. Parasiya, Paresh Nimodiya

ABSTRACT
In General, the structure in high seismic areas may be susceptible to the severe damage. Along with gravity load structure has to withstand to lateral load which can develop high stresses. Now a day, shear wall in R.C. structure and steel bracings in steel structure are most popular system to resist lateral load due to earthquake, wind, blast etc. The shear wall is one of the best lateral load resisting systems which is widely used in construction world but use of bracing will be the viable solution for enhancing earthquake resistance. So there is a need of precise and exact modeling and analysis using software to interpret relation between brace frame parameters and structural behavior with respect to conventional lateral load resisting frame. There are various softwares used for analysis of different type of lateral load resisting system such as, E-TABS, SAP2000, STADPRO, etc. In this paper, to evaluate seismic performance of the of the building, 15 storey, 20 storey and 25 storey RCC building model is considered with MR frame, SW frame, X-braced frame, Inverted-V and V braced frame for analysis. The analysis is carried out using three different time histories and response of the building is obtained in terms of storey shear, storey drift and storey displacement to choose best alternative. To evaluate the different parameter linear time history method is carried out using e-tabs software.

IJAERS/Vol. III/Issue III/April-June, 2014/40-42

Authors:Roshan Megharaj Dabhade. V.C. Kale, Swapnil S. Kulkarni

ABSTRACT
The failure of leaf spring is attributable to its fatigue loading. Cyclic loads of a constant or varying magnitude and direction act and on the suspension system of the automotive that is sustained and borne by the leaf spring while the vehicle runs along the road. Pot-holes and bumps add the shock loads. This work aims to focus its research over assumption of the constant amplitude loading of the case study of the leaf spring for a passenger car. Finite element modeling would be employed to evaluate the existing design while offering a precursor to the alternatives for design. Feasible design alternatives would be started using F.E. methodology. The benchmark design would be validated in advance for offering credibility to the F.E. model. Further analysis would be done for recommend of the most suited design for leaf spring. HyperMesh/ Nastran & MSC Fatigue are considered for solving fatigue is considered for solving the FE model & simulating results.

ABSTRACT
Piston is one of the important component in internal combustion engines. They are employed in different type of engines from single cylinder engine to large multi cylinder diesel or petrol engine. The piston is one of the most critically loaded components as it experiences cyclic loads in the form of thermal and pressure load during its service life. Fatigue is a major consideration in the design and performance evaluation of materials, components and structures since most of the all mechanical failures are attributed to fatigue fractures, especially in engine parts. The investigation emphasized that this cost could be significantly reduced by using proper and efficient design, manufacturing & various processes. Such studies are necessary to enhance the competitiveness of the vehicle components and their application in the automotive industry. Efficient design manufacturing methods help in enhance performance and efficient operation of piston & finally operation of engine. Shoot peeening is one of the processes to enhance fatigue life of component and there is scope of study effect of shoot peening on fatigue life of piston.

UTILIZING IDENTIFYING ALTERNATIVES FOR CONVENTIONAL PIPES USING CAE TECHNIQUES FOR PLASTIC COMPOSITES

IJAERS/Vol. III/Issue III/April-June, 2014/53-54

Authors:Manju Sudhir Nirale,Prof. S.G. Dambhare, Swapnil S. Kulkarni

ABSTRACT
The conventional material used for a general purpose pipe carrying fluid has limitations while being attempted for use under high stress environmental conditions. The current application which calls for underground use of the pipe carrying fluids (including water or gases) is being designed to withstand harsh conditions of crushing pressure (and/or corrosive environment). Use of general purpose steel or any such material may not warrant its usability under these trying conditions. The proposed work would attempt to find an optimal solution in terms of weight (and/or cost) while complying to the performance standards set in the industry for such applications. The use of fiber reinforced plastics and/or metal impregnated plastics (metal pipe with suitable thick plastic coatings) appear to be suitable candidates for this dissertation work. The design alternatives would be evaluated using FEA software for structural strength experienced under practical working conditions. The same would be tried and tested through physical experimentation while validating the Design for this work.

USING FEA FOR VIBRATION OR STRUCTURAL ANALYSIS OF GEAR FOR DETERMINING SUITABLE GEOMETRY FOR THE APPLICATION

IJAERS/Vol. III/Issue III/April-June, 2014/55-57

Authors:Subodh Suhas Lande, Prof. A.M. Pirjade, Swapnil S. Kulkarni

ABSTRACT
Modal oscillation of gearbox housing walls and other elastic structures is very important for the noise emitted by systems into the surroundings. Modal activity of housing walls is in direct relation with the structure and intensity of noise emitted by the gearbox into the surrounding. Therefore, research of modal activities is of general importance for modeling the process of generation of noise in mechanical systems. The noise emitted into the surroundings by the gearbox is mostly the consequence of natural oscillation of the housing.
It is also necessary to systematically study natural frequency and vibration mode sensitivities and their veering characters to identify the parameters critical to gear vibration. In addition, practical gears may be mistuned by mesh stiffness variation, manufacturing imperfections and assembling errors. For some symmetric structures, such as turbine blades, space antennae, and multi-span beams, small disorders may dramatically change the vibration.

IJAERS/Vol. III/Issue III/April-June, 2014/61-63

Authors:Purushottam Sarjerao Suryawanshi, Prof. T. S. Shikalgar, Swapnil S. Kulkarni

ABSTRACT
Compression springs are coil springs that resist a compressive force applied axially. Compression springs or coil springs have a spring constant and may be cylindrical springs, conical springs, tapered, concave or convex in shape. The changing of compression spring ends, direction of the helix, material, and finish all allow a compression spring to meet a wide variety of special industrial needs. Coil springs can be manufactured to very tight tolerances; this allows the coil spring to precisely fit in a hole or around a shaft. A digital load tester, or coil spring compression tester can be used to accurately measure the specific load points in your metal spring. Compression springs are able to have two entirely different spring rates or a different spring constant associated with its design. Compression springs can be made from non‐magnetic spring wire like Phosphor Bronze or Beryllium Copper.

Authors:Amruta N. Kurnawal, Prof. R.A.Oak

ABSTRACT
Water is vital component in history & survival of human being & all other species. Water management improvements can promote conservation and make best use of our limited water resources, but better management depends upon the ability to accurately measure and control the flow of water. Instrument calibration is one of the primary processes used to maintain instrument accuracy. The results of calibration are used to establish a relationship between the measurement technique used by the instrument and the known values. In the present study, effect of error on the value of Cd was analyzed with the help of experiments. In first step, experiments were carried out by using orifice meter as a model, to analyze the effect of errors on the value of Cd. In second step a data set of calibration curves of three different types of current meters was analyzed. At the last in third step performance of current meter after actual calibration was analyzed. In this present study from the results it was concluded that, no instrument has 100% accuracy. So the results of any experiment should be analyzed by more than one method.

VIEW ON ECONOMICAL HOUSEHOLD DRINKING WATER TREATMENT TECHNOLOGY

IJAERS/Vol. III/Issue III/April-June, 2014/70-73

Authors:R Raj Kishore Singh, Santosh Kumar Sar

ABSTRACT
Man’s search for pure water began in prehistoric times. The quest for pure water can benefit the life and health of every one. Earlier, water treatment methods were developed almost entirely as an art rather than as a science and technology. However, the introduction of the modern and innovative concepts in water purification technology over the past few centuries has played a pivotal role in protecting public health from pathogens and chemicals. As more than a billion people on this earth have no access to potable water that is absolutely devoid of pathogens; technologies that are cost effective and suitable for developing countries must be considered. Sustainable operation of these treatment processes taking into consideration locally available materials and ease of maintenance need to be considered. Furthermore, as per the records of united Nation 2.2 million people died in this world in the year 2004 due to lack of access to safe drinking water illustrating that clean water use is a prime concern in many communities of the developing countries . Contaminated water plays a paramount role in taking numerous lives in these localities for which a number of efforts are being made for accessing safe purified drinking water. Fortunately, sustainably efficient and cheap drinking water treatment technologies are being tried to be adopted worldwide for easy access to clean & safe drinking water.
In the aforesaid project, we had tried to develop “Economical household drinking water treatment technology” using the basic ideas of slow sand filter, some locally available filter material viz. charcoal, bone char, sand, manganese modified sand, clay, rice husk ash, Moringa oleifera residue ash, anthracite and tried to improve the methodology using the RO filter, UV filter and activated carbon filter mechanism. The primary focus was the removal of heavy metals viz. iron, copper & zinc from surface water & ground water by adsorption and oxidation followed by precipitation technique. Among all these adsorption media used, manganese modified sand proved to be a good adsorbent in removal of heavy metals. For oxidation followed by precipitation, the ash produced from Moringa oleifera residue was used which proved to give the best result in removal of heavy metals and also was having the cheapest material cost. A ceramic membrane with locally collected clay, fine sand having fineness modules 2.5 and rice husk was prepared, which also proved to be effective for removal of turbidity and in turn bacteriological contaminants susceptible to turbidity to an appreciable extent.

USING FINITE ELEMENT ANALYSIS FOR ASSESSING THE VIBRATIONS IN THE SILENCER USED IN AUTOMOBILE INDUSTRY

IJAERS/Vol. III/Issue III/April-June, 2014/74-75

Authors:Amit Mahadeo Asabe, Prof. Pravin P. Hujare, Swapnil S. Kulkarni

ABSTRACT
Silencer performs the function of reducing the noise level to acceptable or desirable standards per the norms of regulations towards compliance. In doing so, it experiences pulsating exhaust gases at a high velocity that tends to undermine the structural strength of the various elements of the silencer. The baffles, perforated pipes, body and the mounting parts tend to vibrate as the excitation frequency of the source (engine). The ‘frequency match’ could lead to a response detrimental to the life of the structure. FEA techniques are proposed in this work to avoid resonance. Physical experimentation is proposed using FFT Analyzer. .

FEA has been used to predict the dynamical properties of the gear. Experimental modal analysis has been carried out on the gearbox housing to verify the theoretical predictions of natural frequencies.

STUDY OF EFFECT OF VARIATION OF SHARP CRESTED WEIR HEIGHT AND BASE WIDTH USING LOCALLY AVAILABLE MATERIAL I.E. WOOD

IJAERS/Vol. III/Issue III/April-June, 2014/79-81

Authors:R.T. Jyoti, 2Smita Hailkar, Dr. N.J. Sathe, Swapnil S. Kulkarni

ABSTRACT
Irrigation waters are transported from one location to another using natural or constructed conveyance structures. The cross section of these structures may be opens or closed at the top. The structures with closed tops are referred to as closed conduit sand those with the top open are called open channels. For example, tunnels and pipes are closed conduits whereas rivers, streams, estuaries etc. are open channels. The flow in an open channel or in a closed conduit having a free surface is referred to as free-surface flow or open-channel flow. In India generally open channel is used for transportation of water because manufacturing cost for open channel is low in relation to closed conduits. Generally the best easiest and the simplest economically beneficial method is used for discharge measurement. And for this discharge measurement the weir section or notch is the simplest method which is used all over the world.
Weirs allow water to be routed through a structure of known dimensions, permitting flow rates to be measured as a function of depth of flow through the structure. Thus, one of the simplest and most accurate methods of measuring water flow in open channels is by the use of weirs.

IJAERS/Vol. III/Issue III/April-June, 2014/84-85

Authors:Sachin Ramdas Jadhav, Sunil Hiraman More, Swapnil S. Kulkarni

ABSTRACT
Sheet metal forming problems are typical in nature since they involve geometry, boundary and material non-linearity. Drawings part involves many parameters like punch and dies radius, clearance, lubrication, blank holding force and its trajectories etc. So designing the tools for part drawing involves a lot of trial and error procedure. To reduce number of costly trial error steps, the process can be simulated by using finite element packages. Even the finite element package gives an approximation towards the solution. The dissertation work is relevant in the context of developing a cost effective die with a lower lead time through the phase of Design, Development, Trials and Testing, Pilot lot production & Regular supply. The Deep draw process being critical to evaluate offers higher scope for study and research while addressing the most suitable design for the Draw Die. Sheet-metal die is an inseparable constituent of the development process of any given automotive or consumer appliance. In most of the cases, this accounts for a high proportion in the tooling needs of the large size and structural member in any automotive like the chassis and the BIW.

Authors:Purushottam Dumbre, Prof. A.K.Mishra, V.S.Aher, Swapnil S. Kulkarni

ABSTRACT
The weight of the vehicle is going on increasing due to additional luxurious and safety features. The increasing weight of the vehicle affects the fuel efficiency and overall performance of the vehicle. Therefore the weight reduction of the vehicle is the real need of today’s automotive industry. Steering knuckle is one of critical component of vehicle. It links suspension, steering system, wheel hub and brake to the chassis. There is scope to reduce the un sprung weight vehicle. Steering Knuckle is a non-standard part and subjected to various loads at different conditions. Weight reduction of steering knuckle is the objective of this exercise for optimization. Typically, the finite element software like OptiStruct (Hyper Works) is utilized to achieve this purpose. For optimization, Nastran/Ansys/Abaqus could also be utilized. The targeted weight or mass reduction for this exercise is about 5% without compromising on the structural strength.

IJAERS/Vol. III/Issue III/April-June, 2014/93-94

Authors:Aslam Badshah Shaikh, Vivek S Shinde, Swapnil S. Kulkarni

ABSTRACT
The performance of an automotive engine depends on the efficient cooling it in corporate in the system. The engine has a jacket around the hosing for calculating coolant-typically water based that runs around the engine to pick up heat and dissipate it over the radiator which represents a fin of tube construction. This dissertation work would attempt to evolve suitable configuration for the parameters affecting performance. The diameter, pitch, material of the tube or the arrangement of fins could be manipulated for assessing the result over the performance. The aim is to enhance the rate of heat transfer with the surrounding environment while natural ventilation is offered to the radiator (evaporator). CFD, Ansys Fluent would be developed for analytical treatment while preliminary investigation may involve mathematical treatment. The benchmark geometry (existing) would be used for experimentation for validating the analytical model.

It is particularly attractive for processing engine mounting brackets with high strength at desired elongation and hardness, since the porosity of dispersed defects under the action of the pressure is remarkably reduced during squeeze casting. Therefore, to develop suspension parts, such as the knuckle, arm, and structure parts to support the automobile engine, the squeeze casting process was developed with die design and process parameter control.
Advances in modeling of casting processes using smoothed particle hydrodynamics (SPH) could be taken up for study. Three-dimensional simulations of high pressure die casting are planned for case-study for a project with the Sponsoring Company. Development of this work would need both visualization of these systems and the associated simulation for the flow. Comparison of SPH/ Software simulation with experimental results for any casting method (Gravity/ LPDC/ HPDC) shall be considered for this dissertation work.

A TECHNIQUE TO ENHANCE THE DISCHARGE OF A MULTI INTAKE CENTRIFUGAL PUMP

IJAERS/Vol. III/Issue III/April-June, 2014/115-118

Authors:Sumit N.Gavande, Prashant D.Deshmukh, Swapnil S.Kulkarni

ABSTRACT
The pump while operating under a given set of conditions is expected to offer a certain discharge while consuming a given unit of power. The efficiency of the pump is normally evaluated by making assessment of these response parameters. It is observed that higher capacity pumps with single suction pipe introduced a depreciation performance. This work would look into the prospects of designing the suction side of the pump for improving its performance. Design alternatives shall be proposed to reduce the incidence of vortices or turbulence while aiming to ensure the smooth flow for enhanced discharge. Mathematical model shall be offered to investigate the problem at the preliminary phase of study. The design alternatives will be evaluated with the help of CFD techniques in the form of `ANSYS-Fluent’. Suitable attempt is being considered for physical experimentation..

PREDICTION OF SOAKED CBR OF FINE GRAINED SOILS FROM CLASSIFICATION AND COMPACTION PARAMETERS

ABSTRACT
California Bearing Ratio (CBR) is an indicator of sub grade soil strength. In the design of flexible pavements soaked value of this parameter is often used; the evaluation of which through laboratory test is time consuming and laborious. The soil classification and compaction parameters are routinely determined for in-situ and borrow soils used in the construction. In the present study, soaked value of the CBR of fine grained soils is correlated with classification and compaction parameters. The multiple regression analysis was performed on the results of laboratory tests for a large number of soil samples collected from different road projects of Madhya Pradesh (India). The basic soil properties, namely liquid limit, plastic limit, fine content, optimum moisture content and maximum dry density correlate with the soaked value of the CBR. The developed correlation equation is validated from a few independent test data reported in Soil Test Reports of rural roads of Madhya Pradesh and is found reasonably accurate.

ABSTRACT
Due to the strength and volume stability issues, construction on expansive soils is either avoided or the soil is removed and replaced with good soil or is improved by adopting soil improvement techniques. The expansive soils behave like soft soil under wet condition. The technique of granular pile, that is usually employed in improving soft marine clays (i.e. soft soils), can also be applied to improve the behavior of expansive soil (Kumar and Jain 2013, Kumar 2014). The paper presents the results of a model study in which granular pile is installed in prepared beds of expansive black cotton soil. The load-settlement response of the granular pile in unsaturated and saturated state of the soil has been studied. The initial molding water content mixed in the expansive soil at the time of preparation of the test bed was the variable of study. The load test was performed on the pile, just after installation of the pile (unsaturated soil condition) and also after saturating the soil for four days i.e. in saturated soil condition. The test results show that the load carrying capacity of pile decreases as the molding water content increases. Compare to unsaturated state of the soil, the load carrying capacity of a pile in corresponding saturated state is less. The difference between the two values decreases as the initial molding water in to the soil increases.
