【Abstract】 In order to analyze the bending performance of train axles, an axle cantilever bending tester is designed. The fatigue life of the test machine is predicted. The model of the axle cantilever bending tester is established, the appropriate finite element method is selected, and the ANSYS software is used to simulate the test process. The design of cantilever bending tester, the fatigue theory and the basic process of finite element analysis are introduced. The simulation results are analyzed to predict the life of the tester. According to the analysis results, the axle cantilever bending tester has less stress and strain, and the predicted fatigue life can meet the test requirements.更多还原
