摘要

提出用于实现卫星与相机连接解锁功能的包带式解锁支座，对支座解锁时的冲击环境进行分析与探讨。介绍解锁支座结构原理，对支座解锁时的结构响应进行测量及数据分析。采用有限元分析软件进行瞬态分析，对实验及计算数据进行冲击响应谱分析。实验、分析结果表明，解锁冲击主要由解锁支座应变能释放造成；适当减小包带预紧力能降低结构的冲击响应；有限元分析能较精确预示低频冲击环境。为此类解锁装置设计与冲击环境预分析提供参考。

Abstract

A type of clamp-band unlocking support was proposed to realize connecting and unlocking between satellite and camera, and shock environment of the support was studied. Structure of the support was presented, and the structural shock response was measured and analyzed. Transient analysis was conducted through finite element analysis(FEA) software.The experimental and computational data was converted to shock response spectrum(SRS) for comparison. The results of experiment and analysis indicate that the vibration generated by the release of strain energy dominates in the unlocking shock, and proper reducing preload of clamp band can lower the structural shock response, and the finite element analysis can estimate the low frequency shock environment with sufficient accuracy. These conclusion provide reference for the design of this kind of device and the preanalysis of shock environment.
