STUDY OF COST CONTROL ON CONSTRUCTION PROJECT

IJAERS/Vol. III/Issue IV/July-Sept., 2014/01-02

Authors: Prof. Dipak P. Patil, Prof. Pankaj P. Bhangale, Swapnil S. Kulkarni

ABSTRACT
This dissertation work is aimed to minimise and control the construction cost of a construction project. To minimize the cost of a project there are different methods such as quality management, time management etc. In this work I have applied the inventory control system to control the cost of a project. In inventory control system if we applied ABC analysis and EOQ to the project then there will be definitely savings in cost and also avoids wastage of material.
The mathematical module of ABC analysis and EOQ gives the importance of material and its effect on cost of construction project because the cost consumed by the materials in any project is approximately 65% to 70% cost of total project. In this work one case study of construction project of a school building has been considered and the cost required by project with and without material management is analysed.

DEVELOPING QUADRA-STEERING SYSTEM FOR MULTI PURPOSE OF VEHICLE AND GIVE BETTER COMFORT FOR DRIVING

ABSTRACT
Nowadays, the every vehicle existed mostly still using the two wheel steering system to control the movement of the vehicle whether it is front wheel drive, rear wheel drive or all wheel drive. But due to the awareness of safety, four wheel steering vehicles are being used increasingly due to high performance and stability that they bring to the vehicles. A Four Wheel steering (4WS) System named as “Quadra Steering System”. Here in this System both front as well as rear wheels can be steered according to space available for turning. If a car could automatically compensate for an under steer/Over steer problem, the driver would enjoy nearly neutral steering under varying operating conditions. Four-wheel steering is a serious effort on the part of automotive design engineers to provide near-neutral steering. For parking and low-speed manoeuvres, the rear Wheel steer in the opposite direction of the front wheels, allowing much sharper turns. At higher speeds, the rest wheels steer in the same direction as the front wheels. The result is more stability and less body lean during fast lane changes and turns because the front wheels don’t have to drag non-steering rear wheels onto the path. Quadra steer is system that gives full size vehicles greater ease while driving at low speed, and improves stability, handling and control at higher speed. The scope includes commonly used methods found in practice as well as some theoretical methods found in various literatures from other areas of research. A multi-functional four-wheel steering system could improve directional stability, sharp turning performance, and parking performance of a vehicle. From concept validation and controller design of the active pinion, the models have been proven effective to explain dynamic phenomena related to Quadra Steering systems.

IJAERS/Vol. III/Issue IV/July-Sept., 2014/07-09

Authors:Roshan Megharaj Dabhade, Mr. 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.

IJAERS/Vol. III/Issue IV/July-Sept., 2014/10-12

Authors:Deepak Kumar Pachauria, Rakesh Kumar, P.K. Jain

ABSTRACT
This paper presents the results of laboratory model test carried out to study the effect of footing diameter on load carrying capacity of skirted sand. The footing of four different diameters (40 mm, 60 mm, 80 mm and 100 mm) were used on loose sand having embedded skirt inside. The skirts of uPVC pipe of different diameter ( 46 mm, 59 mm, 71 mm and 85 mm) was inserted in the sand centrally in a model test tank filled with sand. The sand was having relative density of 40%. The load tests conducted were analyzed to study the effect of footing diameter on load carrying capacity. The skirt restricts the lateral displacement of sand leading to a significant improvement in the response of the footing. It was seen from the result that on increasing the diameter of footing with constant diameter of skirt the load carrying capacity increases.

ABSTRACT
In India, large quantities of fly ash being generated, as most of our energy demand is met through coal based thermal power station. The fly ash generation is expected to grow further as coal would continue to remain major source of energy at least for next 25 years. The fly ash which is a resource material, if not manage well, may pose environmental challenges. On the other hand, development of transport infrastructure is imperative for rapid economic growth of the country. During the recent past, road transport has come to occupy a dominant role in the transportation system. The use of fly ash in National Highway Roads and embankment construction not only facilitate mass disposal of fly ash but also provide significant benefits in terms of engineering and economic considerations. This Project report emphasis on the proper Management of fly ash in the Construction of National Highway Projects.

DESIGN AND DEVELOPMENT OF AIRCRAFT DROOP NOSE RIBS BY USING OPTISTRUCT

IJAERS/Vol. III/Issue IV/July-Sept., 2014/18-21

Authors:T.Muneiah, E.Bhaskar, Ch.Venkata Rajesh

ABSTRACT
This paper presents the development of a parameterized automated generic model for the structural design of an aircraft wing. Furthermore, in order to perform finite element analysis on the aircraft wing geometry, the process of finite element mesh generation is automated.
The generic model that is developed in this regard is able to automate the process of creation and modification of the aircraft wing geometry based on a series of parameters which define the geometrical characteristics of wing panels, wing spars and wing ribs. Two different approaches are used for the creation of the generic model of an aircraft wing which are “Knowledge Pattern” and “Power Copy with Visual Basic Scripting” using the CATIA V5 Software. A performance comparison of the generic wing model based on these two approaches is also performed.
In the early stages of the aircraft design process, an estimate of the structural characteristic of the aircraft wing is desirable for which a surface structural analysis (using 2D mesh elements) is more suitable. In this regard, the process of finite element mesh generation for the generic wing model is automated. Furthermore, the finite element mesh is updated based on any changes in geometry and the shape of the wing panels, wing spars or wing ribs, and ensure that all the mesh elements are always properly connected at the nodes. The automated FE mesh generated can be used for performing the structural analysis on an aircraft wing.
Topology optimization has for a considerable time been applied successfully in the automotive industry, but still has not become a mainstream technology for the design of aircraft components.. Also, aircraft components are often stability designs and the compliance based topology optimization method still lacks the ability to deal with any buckling criteria. The present paper considers the use of the compliance formulated topology optimization method and detailed sizing/shape optimization methods to the design of aircraft components but also discusses the difficulties in obtaining correct loading and boundary conditions for finite element based analysis/optimization of components that are integral parts of a larger structure.

Authors:Dr. D. N. Mishra*, Dr. P. K. Jain, Dr. P.N. Mishra

ABSTRACT
Health Care industry is very clearly divided into two parts. Government stresses very much on the health industry as this sector directly impacts the common man. On the other hand it is a very profitable industry and so the private players are also taking the due interest. As the objectives of the two players are entirely different their working, the stakeholders involved and the customers’ satisfaction also vary to a great extent. Healthcare is one of India’s largest sectors, in terms of revenue and employment, and the sector is expanding rapidly. The private sector accounts for more than 80% of total healthcare spending in India. This paper gives a review about the health care industry in Indore, Madhya Pradesh.

EVALUATING THE EFFECT OF SHOT PEENING AS A SURFACE TREATMENT PROCESS FOR INDUCING RESIDUAL COMPRESSIVE STRESSES USING FEA

IJAERS/Vol. III/Issue IV/July-Sept., 2014/30-33

Authors:Dinesh Mahajan, D.B. Sadaphale , Swapnil Kulkarni

ABSTRACT
"The impacting steel balls over the surface of the component induces plastic strain/ deformation. This causes a change in the micro-structure at the surface over few microns deep that enhances the mechanical properties of the material. This is due to the increased resistance to failure (slip) due to the changed orientation of the grain. The phenomenon is aimed for study at the premises of the sponsoring Company in the context of CAE analysis. The explicit solver to be engaged for this study would offer insights into the extend of plastic deformation or residual stresses in the component for deriving appropriate factor for predicting the mechanical properties. This work would be backed up with the relevant standard data and/or the testing/experimentation for research at the associates of the Sponsoring Company. This process results in enhanced fatigue life by virtue of the beneficial compressive residual stresses."

BEHAVIOR OF CIRCULAR FOOTING RESTING ON TWO DIMENSIONALLY AND THREE DIMENSIONALLY SKIRTED FOUNDATIONS IN MEDIUM DENSE SAND

IJAERS/Vol. III/Issue IV/July-Sept., 2014/45-47

Authors:Ravi Gupta, Rakesh Kumar and P.K. Jain

ABSTRACT
This paper presents the results of model test conducted to study the load-settlement behaviour of two dimensionally and three dimensionally confined medium dense sand. Tests were performed in both conditions, unconfined and confined case. In the present study a circular footing of 50 mm diameter used. The diameter of skirt was fixed and skirt height was varied (75 mm, 100 mm, 125 mm and 150 mm).The results showed the load carrying capacity increases in case of confined sand as compared to unconfined sand and the load carrying capacity of three dimensionally confined case for all skirt height is more than two dimensionally confined case and unconfined case. It was concluded that in case of three dimensional confined sand resist lateral and longitudinal both displacement of sand underneath the footing while in case of two dimensional confined sand it resist only lateral displacement of sand underneath the footing so its load carrying capacity is less as compared to three dimensional case due to this it leads to significant increase in load carrying capacity of footing. The recommended skirt height that gives maximum load carrying capacity improvement are discussed and presented.

CAE ANALYSIS FOR FATIGUE FAILURE FOR COILED SPRING LIFE ENHANCEMENT IN PRESS MACHINE STAMPING OPERATION

IJAERS/Vol. III/Issue IV/July-Sept., 2014/48-51

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

ABSTRACT
Springs are basically an elastic element, which can deflect or distort under load and returns to its original shape when load is removed. As it considered to be a flexible element hence used to exert a force or torque and also at same time to store energy. This force may be push or pull or may be radial. So these springs are mainly used in the industry as absorbing element as well as restoring the initial position of a part upon displacement for initiating a given function. In mechanical field there are number of components are subjected to cyclic loading or repeated stresses and have to withstand it over a number of cycles beyond 107. Those elements may cause failure depending on the material, component design, loading or other factors. In this project, we considered the four variants of spring as its application is in the dies to hold the metal sheet during blanking (stamping) operation. One of the variant is considered as standard specimen and accordingly study and design analysis of standard specimen is done (In Hypermesh, NASTRAN and MSC Fatigue), by finding the both static force and dynamic forces in terms of fatigue life. Therefore, by following the standard specimen, the other three specimens are studied with respect to dimension and geometry (Using Hypermesh, NASTRAN and MSC Fatigue) and analyze the new variant of springs with the standard one by considering the stress and fatigue life.

Authors:S. V. Jaswandkar, P.N.Deshmukh, Prof. P.S.Desle, Swapnil S Kulkarni

ABSTRACT
Designing the handle bar assembly of a two wheeler holds many challenges together with valuation of the structural strength of the mating components. While the handle bar is subjected to buckling, the housing and the other frame experiences tensile, compressive and shear stress. The situations during braking and the forces generated due to road bumps and pot holes can increases the problem. This work shall focus on conducting linear stress analysis while evaluating and rationalizing the loads. Finite element analysis of handle bar assembly is carried out using Altair solver code RADIOSS. In this study the handle bar assembly is excited with acceleration obtained from road load data to evaluate the strength of mountings on handle-bar. Model is prepared using Catia V5R20, Pre processer Hyper Mesh and Post processing is done using Hyper View. The Finite element analysis outcomes are also well allied by the experimental results in which failure site and pattern is accurately matched. Further modifications have been made in design to come across the strength requirement.

IJAERS/Vol. III/Issue IV/July-Sept., 2014/72-76

Authors:Swapnil Killedar, Prof. Sanjay Deodas, Swapnil S. Kulkarni

ABSTRACT
Machine Frames are normally cast or fabricated with the new trend pointing to assembly using extrusions with fasteners. For most production applications of machine tool structures, (gray cast iron) metal castings remain the primary choice because of cost, ease of sourcing, good damping with relatively high strength, good machinability and well-established and consistently achievable manufacturing and processing requirements. However, fabrications are normally the preferred choice for low volume production of large structures, Although the more robust construction for SPM prefers fabricated sections of square tubes. For this work, the base Frame of `Pressing SPM’ is being designed as a fabricated structure followed by Finite Element Modeling and Analysis to verify its strength under the given working conditions. The SPM frame is modeled using commercial software and all the specification was accordingly followed the relevant drawing standard. The geometry of machine frame is modeled using competent software CATIA V5 R18 software. The FE model is prepared with the help of hypermesh software while doing so square tubes are mesh with the 2D Quad element &solid partis mesh with Second order 10 noded tetra elements. The attempt is to identify alternatives i.e. Diagonal, Parabolic, Trapezoidal, Cast machine frame etc. for sufficing the task while recommending the best solution to the given problem. Offering structural strength while incorporating simplicity in design and process of development shall be the objective of the work. The thesis would be validated with analogy for the raw material test piece to be tested in a laboratory. A three point bending test on test specimen is done on UTM and result is compared with FEA result of the specimen.

CRACK DETECTION IN CANTILEVER BEAM BY VIBRATION TECHNIQUES

IJAERS/Vol. III/Issue IV/July-Sept., 2014/80-86

Authors:Kaustubha V. Bhinge, P. G. Karajagi, Swapnil S.Kulkarni

ABSTRACT
In this work we try to establish a systematic approach to study and analyze the crack in cantilever beam. This work addresses the inverse problem of assessing the crack location and crack size in various beam structures. The study is based on measurement of natural frequency, a global parameter that can be easily measured at any point conveniently on the structure. In theoretical analysis the crack is simulated by a spring, connecting the two segments of the beam. The catachrestic equation obtained from the vibration analysis of Eluer-Bernoulli beam is manipulated to give the relationship between the stiffness & location of crack. The model of beam is generated using finite element method. To begin with, natural frequencies for uncracked beam found out by finite element analysis. Crack has been developed of known dimensions at known location. The induced crack causes reduction in natural frequency. Plots of the spring stiffness verses crack location are obtained for the three lowest transverse mode using the derived relation. There common intersection point will give the crack location & corresponding stiffness. Further the crack size can be estimated from the standard relation between stiffness & crack size. The numbers of cases are evaluated & error in the prediction of crack size & location is less than 4%.

EFFECT OF HEAT TRANSFORM ON OFFSET SPLIT CHANNELS

IJAERS/Vol. III/Issue IV/July-Sept., 2014/99-101

Authors:M.V.S.N Ramanjaneyulu, Dr. Y.V Hanumanth Rao

ABSTRACT
The increased circuit density on today’s computer chips is reaching the heat dissipation limits for air-cooling technology. The direct liquid cooling of chips is being considered as a viable alternative. Finding a method for effective cooling for the electronic chips is the aim of this project. The small hydraulic diameter increases the heat transfer coefficients. An offset split straight mini channel with hydro dynamically developed and thermally developing flow is considered for study and the results are compared with that of a straight mini channel. Offset split mini channel is made from aluminum of 30 mm square with 11 mm thickness. DI water and Al₂O₃ nano fluid of concentrations 0.1% and 0.5% are used as the heat transfer fluid. Reynolds number is varied from 700 to 2000. The results indicates that heat transfer is increased by 65% in the case of offset split mini channel than straight channel and nano fluid increases the heat transfer by 20% as compared to DI water.

EFFECT OF MASS ATTACHMENT ON NATURAL FREQUENCY OF FREE-FREE BEAM: ANALYTICAL, NUMERICAL AND EXPERIMENTAL INVESTIGATION

IJAERS/Vol. III/Issue IV/July-Sept., 2014/102-105

Authors:Prof. M. S. Kotambkar

ABSTRACT
In this article the mass loading effect due to accelerometer on the natural frequency of slender beam in free-free configuration has been investigated. Free-free configuration is selected as it is easier to replicate these boundary conditions in both experiment and analytical model. Also it is customary to validate the geometric model by comparing results with experiment in free-free condition. Natural frequencies obtained using accelerometer and FFT analyze are lower than obtained analytically or numerically using software based modal analysis. The difference could be attributed to the change in the boundary conditions, variation in geometric model simulating the real system, change in material properties and effect of accelerometer mass with its location on the beam.
Present work develops an analytical formulation to compute modal properties of a mass loaded beam. The beam is considered as Euler-Bernoulli beam with additional mass effect is modeled by considering jump in shear force at the location and modal properties are investigated. The analytical and numerical model can be used to simulate mass loading in general although experiment is performed specifically to study effect of accelerometer mass.

APPLICATION OF FINE PIERCING PROCESS FOR ROLLER CHAIN LINK PLATE TO INCREASE BREAKING LOAD OF ROLLER CHAIN

IJAERS/Vol. III/Issue IV/July-Sept., 2014/106-110

Authors:Patil R.A., Prof. Gaikwad B.D., Swapnil Kulkarni

ABSTRACT
The hole quality in the sheet metal manufacturing is directly dependent on the die design and process parameters. In conventional piercing process, the hole surface features normally consist of the die-roll, shear surface, cracks, and burr. The secondary operations such as shaving, reaming, and grinding are needed for achieving the smooth hole surface without any cracks. The link plate of roller chain is manufactured by conventional blanking and piercing operation. In assembly of roller chain only shear zone of hole comes in contact with pin, so less contact area between pin and bush causes uneven bending stresses as well as shear stresses in the pin while chain is in working condition. Therefore elongation in the chain due topin and bush wear, which decrease the braeking load and life of chain. The purpose of this study is to increase the contact area between bush and pin which automatically will increase the life and the breaking load of the chain.The fine-piercing process, referenced tothe fine-blanking principle, is used to produce the precise-dimensioned holes in the roller chain link plate parts with smooth-cutsurfaces over the whole material thickness in a single operation. In this study, the stresses on link plate and pin were investigated by finite-element method (FEM) for both conventionally piercing and fine piercing of link plate. The breaking load of chain was checked on UTM for both roller chains when conventionally pierced link plate and fine pierced link plates are used in assembly of chain.
The results showed that an application of fine piercing processes in link plates of roller chain results superior fine-pierced hole surface could be achieved. Furthermore, the use fine piercing process increases shear length in hole. The increase in shear length increases the contact area between pin and bush, therefore wear between pin and bush reduces. The reduction in wear minimizes stresses on pin and link plate and increases breaking load and life of chain.

ABSTRACT
Biodegradable polymers can potentially be combined with natural fibers to produce biodegradable composite materials. In this research program, PLA (Polylactide) was used in combination with Jute fabric to generate bio-composite by compression molding technique. Tensile, flexural and impact properties of bio-composite were determined. The result from mechanical testing revealed that use of Jute fabric with PLA resulted, increase in tensile strength and tensile modulus by 23% and 14% respectively. Flexural strength and impact strength were found to be increased by 8% and 102% respectively. However the use of Jute fabric with PLA reduced the flexural modulus by 13% and further research is in progress to validate and authenticate the reason, why the flexural modulus is reduced. Scanning electron microscopy investigation also showed good bonding between the Jute fabric and PLA as there were no air voids. Water absorption results reported 0.62% increase in weight of the bio-composite for 24 hrs conditioned time. The findings of this research create the scope of use of the Jute fiber/ fabric for making fully biodegradable composites for potential application as architectural interiors in building construction sector.

ABSTRACT
Existing known meta-search engines are built for access of multiple search engines. According to particular search keyword i.e. user input search text, meta-search engine returns a list of search results by filtering duplicate entries / search results. This paper discusses a new ranking method for retrieval of URLs in meta-search engine using fuzzy logic.
