摘要
以月球车的结构机构分系统和移动分系统两个主要承载结构系统为研究对象,建立月球车整器有限元模型,对着陆器与月球车两种连接方式的静力学和动力学进行了仿真分析和结构减重优化,并进行了正弦振动、随机振动和静力承载试验等力学环境试验验证,为确定两器连接方案奠定理论和试验基础。
The two main load-supporting structures of lunar rover which were structure-mechanism subsystem and motion subsystem were served as the study objects in this paper.The finite element model of the whole rover was established.The statics and dynamics of the two connections of the lander and rover were analyzed by the simulation and the structure was optimized to reduce the mass.The sinusoidal vibration,random vibration and static loading test were made.The study was provided the theory and test base for the connection determination of the lander and rover.
