Fatigue Life Analysis for Motor Base of Vehicle Glass Lifter Based on ANSYS Workbench

It is important to analyse the fatigue life of components. We introduced the mechanism of metal fatigue, and systematically discussed the basic methods of fatigue life analysis and its development. The use of nominal stress method and the law of Miner in the fatigue damage accumulation theory are highlighted. The fatigue life analysis for motor base of the glass lifter was completed using this theory on ANSYS Workbench platform and according to the result, structure optimization was completed to make its life longer.
