中文摘要：

卫星在发射过程中所处的恶劣动力学环境会增加其失效概率,要保证卫星发射成功,需要尽可能降低传递到卫星的振动幅值,保证航天器及其元件的可靠性。基于形状记忆合金（SMA）设计出了一种安装在适配器和卫星之间的隔振器。分别设计没有SMA隔振器和添加SMA隔振器两种状况下的整星隔振实验以检验SMA隔振器的隔振效果。对比两种状况下的振动幅值响应曲线发现,SMA隔振器能够有效地隔离振动,表现为低频隔振效果不明显,而高频段隔振效果好。

英文摘要：

The severe dynamic environment during spacecraft launch will increase its failure probability,therefore,for the successful launching of spacecraft,the amplitude of vibration transferred to spacecraft must be decreased so as to ensure the reliability of the satellite and its components. Therefore,a whole-spacecraft vibration isolator was presented which is installed between the adapter and the spacecraft. The major component of the vibration isolator was made up of the shape memory alloys（ SMA）. The experiment of wholespacecraft vibration isolation with SMA vibration isolator and without SMA vibration isolator were designed to examine the effects of SMA vibration isolator. By comparing the vibration amplitude response curve of two cases the resnlts showthat the SMA vibration isolator can effectively isolate the vibration,characterized by not obvious effect on lowfrequency vibration isolation and good effect on high frequency vibration isolation.
