In this work first we did the experimental bending test of conventional material then we designed the composite sections by using Finite Element Analysis. For those dimensions we manufacture the composite sections using glass fiber and epoxy resin. Further we did the experimental test of composite material and then we compared the both conventional and composite materials for weight reduction.

In internal combustion engine, piston is one of the important components parts defined as cylindrical components that moves up and down in the cylinder bore by force produce during the combustion process. The features of the piston are piston head, piston pin bore, piston pin, skirt, ring groove, ring land and piston ring. In this work the connecting rod of a Kirloskar TV1 diesel engine producing a rated output of 5.2Kw at 1500rpm is considered for the study. Load curves are obtained from the pressure crank angle plots. Gas forces and inertia forces are calculated from these curves. Finite element analysis software ANSYS13 is used to study the stress distribution and deformation in the Piston. The dimensions are physically measured to obtain the CAD model of connecting rod in CATIA V5. Since the weight of the piston has considerable influence on its dynamic behavior, an optimization study was performed on a Aluminum ...

For this project an open lipped C-channel made up of Aluminium alloys and the Cold formed steel alloys are used. For this purpose, a finite element model is developed using ANSYS and its accuracy is validated using experimental results. The study showed that the ultimate load of the open lipped channels under compression varied greatly with the perforation position. The Comparisons of the finite element results and the test results are also made and conclusions are drawn on the basis of the comparisons. The main aim of the project is to determine the buckling strength of the Cold formed steel and aluminium alloys used in structural applications having different combinations of circular perforations and comparison between the experimental and FEA results.

The various parameters considered for this study are Young Modulus, Poisson ratio, compressive/ buckling strength for a constant weight per unit length ratio. Also the prime objective of this present work is to study and reduce the weight of the sections keep the strength of composite material same as conventional material mild steel based on compression test which is carried by digital UTM (Universal Testing Machine) and as well as by FEM (Finite Element Method) software.

Spiral bevel gears, in comparison to straight or zerol bevel gears, have additional overlapping tooth action which creates a smoother gear mesh. This smooth transmission of power along the gear teeth helps to reduce noise and vibration that increases exponentially at higher speeds. Currently the bolero pickup vehicle of Mahindra Company is running with a pinion present in the differential gear box having 11 numbers of teeth. By reducing number of teeth on pinion, we can increase the torque. So we carried out this work to design a new pinion suitable to fit in the bolero pickup vehicle. Only the number of teeth are reduced by keeping all other dimensions same to fit the new pinion in the same housing.

In this paper, noise and vibration approach is described for condition monitoring of spiral bevel gears. A fatigue test rig is developed to test the differential gearbox of an automobile using NVH approach. Experimental tests are conducted on test spiral bevel crown wheel and pinion used in differential gear box to study the noise and vibration characteristics of the gears during operation and also to determine the fatigue life of given spiral bevel gears pair. The test gears are loaded with rated torque with a factor of safety of two, until the pinion fails. Correspondingly the data are logged to record the noise and vibration of the gear pair. The vibration and noise signals are acquired experimentally on time response, and then, these are plotted on frequency response for three different cases viz new gear pair, used gear pair and gear pair after breaking of one tooth of the crown pinion. By studying the characteristics of noise and vibration spectrum condition monitoring and fault diagnosis of the given differential gearbox is possible. By onboard measurement of noise and vibration, early detection of failure of spiral bevel gears pair during operation is accomplished.

This paper discusses the experimental setup with the noise and vibration analysis approach to determine the signature of failures of spiral bevel gears. The proposed experimental setup seems promising for further research and development in the fatigue testing of spiral bevel gears. The Crown pinion and wheel assembly is used for the testing. The pinion is connected to the electric 3 phase AC motor of 75HP with a suitable coupling and the crown wheel is mounted on the half axle shaft, which in turn is connected to an electric dynamometer. The speed/torque of electric motor and the load applied by the dynamometer can be varied. The acoustic sensor is mounted near the differential gear box and the accelerometers are mounted on the Pinion bearing, Crown...
