| Abstract: | 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. |
