摘　　要：提出了一种轮履复合式载人月球车.该车由两独立驱动的转向前轮和两独立驱动可轮履转换的履带系统组成.结合月壤地面力学特点,利用MBD-DEM双向耦合仿真技术对该月球车越障性能进行了仿真分析.仿真结果表明,在一定的重载下,轮履复合式载人月球车具有较好的越障性能,能满足大范围复杂月面的行驶要求.In this paper,a new type of lunar rover is proposed.The vehicle is composed of two independently driven steering front wheels and two independently driven track systems with wheel track conversion.According to the mechanical characteristics of lunar soil,the obstacle surmounting performance of the lunar rover is simulated and analyzed by MBD-DEM bidirectional coupling simulation technology.The simulation results show that under a certain heavy load,the wheel-track combined manned lunar rover has better obstacle surmounting ability,and can meet the driving requirements of large-scale complex lunar surface.
