摘要

为降低卫星受到的来自于运载火箭的振动和冲击载荷，针对柔性卫星整体隔振，提出一种采用高频解耦型磁流变阻尼器的新型整星隔振平台。在理论分析的基础上，设计并制造了新型整星隔振平台、锥壳适配器和模拟卫星，搭建整星隔振系统，进行整星隔振性能试验。对比采用新型整星隔振平台、采用常规磁流变阻尼器隔振平台和采用锥壳适配器时的隔振效果，得到如下结论：新型整星隔振系统的隔振效果明显好于使用传统锥壳适配器时的情况；采用高频解耦型阻尼器能帮助隔振平台减小高频传递率，改善高频隔振性能。试验结果验证了理论分析的正确性。

Abstract

In order to reduce the satellite by rocket from all kinds of vibration and impact load,in this dissertation, new semi-active whole-spacecraft vibration isolation (WSVI) platform is presented. In the WSVI, the magneto-rheological (MR) damping technique is adopted and utilized. the PAF, the proposed WSVIP and the satellite model are designed and manufactured, and then the WSVI system is assembled. The experiments of WSVI are carried out. Furthermore, the isolation performances of the WSVI system 、the conventional MR damper vibration isolation platform and the conical adapter are evaluated and compared. The results prove that, the passive isolation effect of the WSVI system is significantly batter than the conical adapter; high-frequency decoupled MR dampers in the WSVI system can help vibration isolation platform to reduce high frequency transmission rate and improve high frequency vibration isolation performance.
