摘要

摘　要：对于中小型航天器空间对接，可以考虑采用柔性对接杆来替代缓冲机构实现对接碰撞的缓冲功能。首先利用有限元理论建立杆-锥式空间对接碰撞的简化模型，分别通过频谱分析、模态分析与碰撞力波形分析等方法，探讨了柔性杆在对接过程中的碰撞振动规律。

Abstract

Abstract: To medium and small-sized spacecrafts’ docking process, it’s feasible to consider a flexible probe based on probe-cone docking mechanism without buffering to reduce the docking impact shock. In this paper, a simplified probe-cone docking impact model is built using finite element method firstly; the impact vibration modals in docking process are analyzed based on the finite element model. By modal analyzing of the elastic beam and phase-frequency analyzing of impact force and transverse velocity, the relationship between impact and vibration modal of probe is founded.
