【Abstract】 For the two-stage planetary gear transmission system, in order to reduce the system vibration and improve the system performance, the tooth profile modification method and dynamic modeling research are carried out. Based on this,the influence law of the modification parameters on the tooth frequency amplitude of the dynamic meshing force of the system is studied, and the design range of the tooth profile modification parameters is determined. The non-inferior solution set of the tooth profile modification parameters is obtained, and the minimum amplitude corresponding to the meshing frequency of the internal and external gear pairs is taken as the goal to determine the tooth profile modification parameters of the system. The dynamic response analysis of the unmodified and modified gear system is carried out, and the feasibility of the design method of the system tooth profile modification is verified. The results show that reasonable modification parameters can effectively reduce the vibration of the system.更多还原
