文摘

Analysis about a certain company’s gasoline engine crankshaft system with dynamics of multi-body, analysis about the crank which work conditions are worst with the forcing displacement method for finite element analysis, based on the finite element analysis results and the load history to analysis fatigue and Take the experimental verification. The results show that the results based on the finite element analysis of fatigue analysis and the experimental results were very close, and the analysis method is more simple and high accuracy.
