基于月面巡视探测器与着陆器连接力学性能的仿真分析与试验验证

Study of Simulation and Test Based on Connection Mechanics Performance Between Lunar Rover and Lander

月面巡视探测器中的结构机构分系统和移动分系统是主要的承载结构,需承受发射段由于运载火箭产生的严酷的振动激励载荷,该载荷经过着陆器及连接边界传递后,在巡视器上会不可避免的产生"放大效应",为了尽量降低这种放大效应,减轻巡视器在发射段的承载载荷,着陆器与巡视器的连接方式是主要影响因素。文章以巡视器两个主要承载结构系统为研究对象,通过仿真分析、结构减重优化及试验验证,论证了应用在着陆器与巡视器上的两种连接方式的可行性和合理性,解决了巡视器与着陆器的连接问题。

Structure-mechanism subsystem and motion subsystem are the important load-supporting structure of lunar rover. They need to bear the stern mechanics vibration load resulted from the launch vehicle. The load will be magnified because of elastic structure and connection boundary transfer. In order to reduce the load acting on the lunar rover, the connection method between the lander and lunar rover is the most important factor. The paper tries to adopt numerical simulation, structure optimization and test validation based on structure-mechanism subsystem and motion subsystem, and demonstrates the feasibility and rationality of two connection method. Finally, the paper resolved the connection problem between lunar rover and lander.
