在随机振动试验中,为防止卫星过试验现象的出现,通常需要应用带谷试验方法对卫星进行合理的激励。带谷试验方法主要分为主动带谷试验方法和被动带谷试验方法两类。文章首先对两种带谷试验方法的实现方式分别进行了阐述,随后应用两颗卫星分别进行主动带谷和被动带谷试验的实例,分析探讨了带谷试验方法工程应用的有效性。 In the random vibration test, in order to prevent the occurrence of satellite over-test, it is usually necessary to apply the valley test method to properly satellites. Valley test method is mainly divided into active Valley test method and passive Valley test method two categories. The article firstly elaborates the realization methods of two kinds of valley test methods respectively, and then uses the two satellites to carry out the experiments of active valley and passive valley respectively. The effectiveness of engineering application of valley test is discussed.
