嫦娥三号巡视器-着陆器释放分离过程关键力学问题分析

摘要

针对嫦娥三号探测器两器释放分离过程几个关键力学问题,给出两器释放分离过程的主要风险点与影响参数,应用ADAMS建立两器释放分离全过程仿真模型,开展了全过程动力学仿真与相关试验.分析得到可适应安全释放分离要求的着陆器最大着陆姿态边界与关键性能参数,为两器释放分离提供了理论支撑与依据.%Several key mechanic problems during the release and separation of the Chang'E-3 probe are revealed.The main risk points and influentical parameters of the separation process are given.The simulation model of the whole process of the release and separation is established by using ADAMS.Then the dynamic simulation and related experiment are carried out.The main risk points and influentical parameters of the two devices are identified,and the maximal landing boundary condiftions of the lander is obtained,which provides basis and theoretical support for the release and separation of the two devices.
