空间对接机构差动式缓冲系统参数设计研究是开展对接机构的工程研制必须解决的首要问题。本文提出了包络寻大法和能量系数法两种能量分配方法 ,由此确定缓冲元件间吸能分配 ,进而确定缓冲元件的特性参数 The research on the parameter design of the differential buffering system of the space docking mechanism is the primary problem that must be solved to carry out the engineering development of the docking mechanism. In this paper, two methods of energy distribution, namely, the envelope finding method and the energy coefficient method, are proposed to determine the energy absorption distribution among the buffer elements and then to determine the characteristic parameters of the buffer elements
