结构星噪声与振动组合环境激励试验及效应研究
Random Vibration and Acoustics Combined Testing and Effect Analysis of Satellites
摘要
Abstract
Due to the limitation of ground environment test technique, only the single-item environment test is used currently to simulate the combined environment during the period of satellite launch and flight. In general, random vibration test or acoustics test is carried on individually. In fact, it is difficult to precisely simulate the combined environment by using either of these methods since the over-tests or under-tests may occur very often in different frequency bands. In this study, with a type of the satellite structure as the object, the acoustics and vibration combined test technique is discussed. The effectiveness and coupling effect of the acoustics and vibration combined test, random vibration test and acoustic test are analyzed and summarized. This study can gave some reference for similar test for other satellite products.关键词
