Load analysis and Multi body dynamics analysis of connecting rod in single cylinder 4 stroke Engine

The main objective of this thesis is performing the detailed load analysis including Multi Body Dynamics(MBD) analysis and to explore the weight reduction opportunities of connecting rod 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 and fatigue parameters acting on the connecting rod and Multi body dynamics analysis to find out the behaviour of the connecting rod with its associated parts while in relative motion. The second case includes performing the optimisation by looking at the possible weight reduction opportunities for connecting rod. The geometric modelling of connecting rod is done by using CATIA V R20 and saved in IGES format and imported to ANSYS workbench, using ANSYS 14.5 workbench the connecting rod analysed for various stresses by applying loads and boundary conditions by using different modules of ANSYS workbench 14.5. Finite element analysis of the connecting rod is done by considering Carbon steel material. Von misses stresses, frequencies with respect to modes; total deformation, buckling analysis, MBD analysis etc. are done. Optimization by weight reduction is carried out by providing elliptical cut out at I-section of connecting rod and analysed for various loads. Finally results are obtained for various load conditions and future scope for the project is defined.
