Parametric dynamical modelling of planetary reducer based on finite element

Abstract

Abstract: Planetary reducer is widely used in vehicles, robots and other equipments, the existence of side clearance has a great influence on the accuracy and service life of planetary gear system. Finite element analysis method and ANSYS APDL are applied to complete the 3D model of planetary reducer, the meshing process is simulated through contact force definition. Contacts and meshing of a 2K-H planetary gear system is accurately simulated and the numerical simulation calculation is carried out through LS-DYNA explicit dynamic solver. The finite element dynamic responses of different tooth side clearances are studied by parameterized modeling. An effective method for the analysis and research of planetary gear system is provided, supplying useful reference for further optimization of the theoretical model.

Key words: planetary gear set, finite element, characteristic analysis, ANSYS
