摘　　要：为了高效合理的利用着陆器有限的内部空间,提出了一种新的月球车搭载方式--侧部搭载,并详细介绍了该方式下的一种锁定释放机构,对月球车释放过程中着陆梯的展开进行了动力学建模,根据该模型在ADAMS中进行了动力学仿真,验证了该机构工作的可行性;分析了影响着陆梯展开释放速度的因素,可对实际结构参数进行合理化选择提供了一定的理论依据。For the reasonable utility of the limit space in the lunar lander, the concept of side-load lunar rover is presented,meanwhile a locking-releaslng mechanism for the side-load lunar rover is introduced in details, Based on a dynamic model to analysis the deployment and releasing of landing ladder, a dynamic simulation is carried out to identify the feasibility and reliability of the locking-releasing mechanism, Factors affecting the deployment velocity of the locking-releasing mechanism are figured out, which provide some available theoretic bases for the configurable parameters.
