摘要
简介了国外月球和火星等探测器软着陆缓冲机构"触地"敏感技术与应用,提出了采用冲击加速度检测的探测器软着陆缓冲机构(足垫)触月敏感触发方案,阐述了敏感触发装置的设计思想,分析了探测器软着陆触月过程的动力学响应,论述了触发装置的冲击加速度敏感检测方式与原理以及电路单元设计。该装置比较适合月球探测器软着陆缓冲机构的结构和工作特点,可以满足制导、导航与控制(GNC)主控系统设计要求。
This paper briefly describes the sensing technologies and applications for overseas Moon and Mars probes,and brings forward a scheme of soft touch-down sensing and initiating through buffering gear （footpad） stroke acceleration detecting. According to the sheme,the device design idea is expatiated. Then on the basis of the analysis of the module dynamics response to soft touch-down process,the paper emphatically discusses the manner and principle of the detecting stroke acceleration and also narrates the design of the electro-circuit unit.
