“…Aiming at the problem that the contact stiffness analysis method of curvic couplings can not consider the contact interface microscopic morphology,an analytical model of the contact interface stiffness was proposed.Through the stress analysis and stiffness transformation,the general model of curvic couplings contact interface stiffness was obtained,and the GW rough surface model was brought into it to obtain the specific curvic couplings contact interface stiffness formula based on the GW rough surface model.Finally,the analytical model results were compared with finite element results.The effect of surface topography on the contact stiffness of curvic couplings was obtained,and the relationship between the normal contact stiffness and the tangential contact stiffness with the preload and tangential force were obtained.The research shows that the analytical model matches well with the finite element results,which proves the rationality of the analytical model and provides a theoretical reference for the preload force and torque design of the rotors with curvic couplings.…”

Influence of the Pre-compression Amount of the Spring Excitation Segment on the Meshing Performance of the Spring Clutch by Yan Hongzhi, Chen Xinyu, Ye Hui, Zhao Peng, Wang Yiwei

“…The self-excitation of the spring clutch is realized through the pre-compression between the excitation coils at either end of the spring and housing to generate frictional torque to energize the spring.The pre-compression amount of excitation coils at either end of the spring has a great impact on the binding property and lifetime of spring clutch.The spring clutch dynamics model is established by using the finite element analysis method.On ABAQUS platform,the speed synchronization of high speed spring clutch output shell and the input shell,the Mises stress and radial displacement of spring under different pre-compression are solved,and then the pre-compression amount condition of the self-exciting meshing of the spring clutch is obtained,and it is compared with the critical amount of pre-compression of clutch obtained by the analytic solution.Besides,the finite element analysis results show that the steady state stress distribution of spring exhibits M shape,that is,the transition coils have peak stress while the middle coils have uniform stress distribution.The basis for optimal design of spring clutch can be provided.…”
