Reliability analysis of the Dual Mass Flywheel damping flange based on Workbench

This article presents reliability analysis of damping flange from dual mass flywheel.In this paper, workbench software wasused to analyze the reliability of the dual mass flywheel damping flange. First, the mechanical model of the damping flange was built based on the dual mass flywheel's force transmission mode as well as the contact analysis model around rivet hole; then the finite element analysis method was used to solve the stress of damping flange based on previous mechanical model. Applied fatigue analysis in Design-life software for damping flange by the stress model from workbench software, the S-N curve was used to fatigue analysis, and gained the fatigue life distribution of the model. Finally, the durability test of the double mass flywheel carried in MTStest bench which deduced that damping flange meet the requirements of the application in the analysis and test.
