可重复使用着陆缓冲器性能及其特点分析

摘要

研究可重复使用着陆缓冲器是降低月球及深空探测任务成本、提高发射频率等的重要途径.根据是否需要利用传动机构将具有可重复使用特性的着陆缓冲器分为了直线式缓冲器和扭转式缓冲器,从结构组成、工作原理等角度分别对两类缓冲器的几种典型进行了分析,并结合研究现状分析了可重复使用着陆缓冲器的多缓冲方法组合性和多功能性,可为我国可重复使用着陆缓冲器的设计提供参考.%The development of reusable landing shock absorber is an important way to reduce the cost of the lunar and deep space exploration and increase the launch frequency. The reusable land-ing shock absorber can be divided into the linear absorbers and rotary absorbers based on the trans-mission mechanism. Typical shock absorbers of these two types were analyzed in the aspects of struc-ture and working principle. The characteristics of combination of multiple absorbing methods and multi-functions were analyzed based on the latest researches to provide suggestions for the design of reusable shock absorbers in our country.
