Static and Vibration Analysis of Manned Lunar Rover Frame Based on Ansys

As lunar exploration projects continue to progress, increasing expectations are being placed upon the efficiency and detection range of lunar surface exploration. For the next stage of lunar exploration projects, a breakthrough technology regarding the utilization of manned lunar rovers is requisite. In view of the driving environment of the lunar characterized by low gravity, uneven surface, and complexity, it is paramount to ensure the safety and stability of manned lunar vehicles in operation. Therefore, the static structure should be checked, and the environment for the frame of the manned lunar vehicle should be set to conduct vibration analysis for the lunar surface. Utilizing the finite element method in conjunction with existing data relating to manned lunar rovers, a finite element analysis model is established. Besides, the Ansys software is utilized to conduct static structural analysis, non-rigid body modal analysis, and vibration analysis of lunar sea driving when the manned lunar rover is fully loaded. The results indicate that the strength and stiffness of the manned lunar rover frame meet the requirements, and the maximum stress and maximum deformation caused by vibration are within the acceptable limits. This study provides a theoretical reference for further research endeavors involving the manned lunar rover.
