| 摘 要： | 文章针对航天器振动试验中较为常见的频率漂移现象,分析了其影响,并结合工程案例讨论了可恢复和不可恢复频率漂移现象的产生机理。尤其针对蜂窝夹层板在振动试验中/后的频率漂移,对两种典型的结构失效模式进行了分析。研究结果可为航天器振动试验中出现频率漂移时的原因分析和航天器结构设计提供参考。

| Abstract: | This paper analyzes the frequency drift in the spacecraft vibration test. The mechansims of the restorable and non-restorable frequency drifts are discussed with practical engineering cases, focusing on the frequency drift caused by two kinds of structural damages of sandwich panels. The results can be used for the cause analysis of the frequency drift in the vibration test of the spacecraft, as well as for optimizing the structual design accordingly. |

| Keywords: | spacecraft vibration test natural frequency shift structural damage structual failure modes |
