The main objective of this thesis is performing the detailed load analysis including Multi Body analysis and to explore the weight reduction opportunities of cam used in Bajaj Pulsar 150c.c engine. This has been carried out by considering the two cases. The first case includes the static load stress analysis to determine various stress acting on the cam and valve, and Multi body analysis to find out the behavior of the cam and valve with its associated parts while in relative motion. The second case includes performing the optimization by looking at the possible weight reduction opportunities for cam. The geometric modelling of connecting rod is done by using UNI-GRAPHICS and saved in IGES format and imported to ANSYS workbench, using ANSYS 14.5 workbench the Cam and valve analyzed for various stresses by applying loads and boundary conditions by using different modules of ANSYS workbench 14.5. Finite element analysis of the cam and valve is done by considering structural steel material. Von misses stresses, natural frequencies with respect to modes are done. Optimization by weight reduction is carried out by providing scooped cut out at cam and analysed for various loads. Finally results are obtained for various load conditions and future scope for the project is defined.
