摘要

摘要:随机振动环境是航天器结构强度设计重点考虑的因素之一. 目前, 在随机振动环境条件下, 航天器结构强度设计采取的方法主要为等效的准静态设计方法, 其等效原则可分为加速度响应等效、位移响应等效以及应力响应等效. 本文重点介绍了3 种等效原则的基本原理、处理方法、国内外发展现状及工程应用情况, 并在综合分析的基础上推荐使用基于位移和应力峰值响应等效的设计方法. 最后针对需进一步开展的研究工作提出了建议.

Abstract:Random vibration is an important part of spacecraft structure design. Now, the main method used in the structural strength design of spacecrafts is equivalent static design method. Its equivalent principles include equivalent acceleration response, equivalent displacement response and equivalent stress response. Respective theories, methods, domestic and overseas research status, advantages and disadvantages and engineering applications are presented. The design method based on the peak values of displacement and stress response is recommended. And the problems in need of further research are finally suggested.
