摘要
将轮式、腿关节式、履带式三种机构结合起来设计了一种月球车,此车对低重力条件下的月球表面实际环境具有良好的适应性。月球车在起伏不平的地表环境中具有独特的动态特性,通过对月球车障碍地形下的越障运动过程进行理论建模和数值仿真,进而建立虚拟样机模型进行动态仿真对比研究,分析了月球车的越障特性,验证了机构设计的有效性。
A lunar rover is designed by combining the mechanism of leg, wheel and track, so it can well adapt to real lunar surface of low-gravity. The lunar rover has special kinetic characteris- tic in uneven terrain. The theoretical model and numerical simulation of movement process of the lunar rover over-obstacle course has been presented. In comparison with the theoretical model, a virtual prototype model has also been built to carry out dynamic simulation, and the over-obstacle characteristic of this lunar rover is analyzed. The results verify the efficiency of the mechanism design.
