摘要：
The double cantilever beam flexible pin structure with interference fit is usually adopted by the planetary gear shaft of large gear gearbox, and the interference fit structure at this location is prone to fretting fatigue. The maximum and minimum values of effective interference are theoretically calculated. Besides, the bending load process of flexible pin is simulated by using the finite element software Abaqus. In addition, the influences of bending load, interference and the depth of carburized layer on contact stress, frictional shear traction and slip amplitude are analyzed. Moreover, the influence degrees of various factors on fretting fatigue damage are investigated, and the S-N curve of flexible pin fatigue life is predicted by utilizing the SWT (Smith-Watson-Topper)critical plane theory method. Furthermore, the bending load fatigue loading test is conducted on several groups of specimens, the S-N curve of the flexible pin test is obtained, and the fretting fatigue damage morphology of the component surface is analyzed after the test. The results show that the influence of bending load on fatigue life is greater than that of the interference, and the depth of the carburized layer. The fatigue life of SWT prediction is in good agreement with the test data. Therefore, numerical simulation analysis can be used to help check the fatigue life of the flexible pin in engineering design. © 2021, Shanghai Jiao Tong University Press. All right reserved.
