Rolling Bearing Finite Element Contact Analysis and Lectotype Design for Lunar Rover Wheel-Legged Mechanism

Abstract:

Taking the wheel-legged lunar rover based on double-half-revolution mechanism as a research object, this paper has made a dynamics simulation for the simplified virtual prototype model of lunar rover under several typical road conditions, with the purpose of obtaining the load applied on each bearing of lunar rover wheel-legged mechanism. On the basis of simulation analysis, static contact analysis for the wheel-leg rolling bearing was made by the finite element analysis software ANSYS. Through the finite element analysis for the rolling bearing, the maximum contact stress and deformation of the rolling body sustained the maximum force were obtained. The results will provide the new analytical method and basis for the optimization and lectotype design of the lunar rover wheel-leg rolling bearing.
