| Abstract: | A case study of simulating a flexible crankshaft and engine block system is used in order to know the accurate forces acting between crankshaft and engine block. The crankshaft, engine block and fly wheel are all included in the crankshaft system and all these parts are treated with Finite Element Method （FEM）. Through the dynamics analysis, different engine loads are obtained with different engine operating conditions. The simulation result shows that the multi-body dynamic analysis of the flexible crankshaft system can describe the dynamics of crankshaft system well. |
