Dynamic Simulation and Endurance Limit Safety Factor Calculation for Crankshaft - Comparison of Single Mass and Dual Mass Flywheel
The crankshaft is the component which transmits dynamical loading from cylinder pressure and inertial loads in engine operating conditions. Because of the crucial importance of its function, crankshaft fatigue life is desired to be higher than the predicted engine operating life. In this study, Puma I5 crankshaft dynamic simulation is performed with multi body dynamics technique. Fatigue safety factors are calculated with the dynamical loadings of engine operating conditions. The effects of single mass and dual mass flywheel on endurance limit are analyzed in this study.
