| Abstract: | Based on finite element method and multi-body simulation, a method for crankshaft strength analysis is described. The transient stress during an engine working cycle is calculated using software MSC Patran and MSC Nastran. Then the crankshaft fatigue strength is analyzed. Numerical simulation shows that the method of crankshaft strength analysis with MSC software is suitable for predicting the durability of crankshaft in engineering. |
