摘    要:针对传统探测器软着陆展开锁定机构复杂、可靠性不高的缺点,提出一种新型软着陆展开锁定机构.该机构压紧、展开和锁定装置共用一套机构,具有展开过程平稳、机构简单、可靠性高等优点.介绍了该新型软着陆展开锁定机构的展开原理,分析了该机构的奇异性,建立了其运动学方程组,获得了主支柱主要参数运动变化规律.研究结果表明,该新型软着陆展开锁定机构在展开过程中无奇异点,展开过程运动平稳.

关 键 词:软着陆机构  展开锁定机构  运动学  仿真

Abstract:The structure of the deployable and lockable soft-landing mechanism for Apollo detector is complex and not reliable.To overcome the disadvantages,a new deployable and lockable soft-landing mechanism for planetary probes is developed.The compressing,deploying and locking devices of the new mechanism share a set of mechanism,and the new mechanism has the advantages of steady deploying,simple construction and high reliability.The deployment and locking theory of the new mechanism is introduced.Then,the singula...
Keywords:Soft-landing mechanism  Deployable and lockable mechanism  Kinematics  Simulation
