Stress and Fatigue Analysis of a Single Cylinder Engine Crankshaft
To perform a stress analysis of a crankshaft over the entire cycle of an IC engine, one has to possess a loading history, i.e. the magnitude of the load should be available for every position of the crankshaft during the cycle. This loading history has been obtained through a dynamic analysis done in MATLAB and used in the finite element based stress analysis performed in SolidWorks Simulation 2019. After finding the optimal mesh using the manual h-convergence method, the FE analysis yielded the results neccessary for the fatigue life predictions at previously chosen critical locations. Fatigue performance of the crankshaft was evaluated both analytically and numerically.
