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。
In order to reduce all kinds of vibration and impact load exerted on a satellite and coming from its carrier rocket, here, a new semi-active whole-spacecraft vibration isolation （WSVI） platform was presented. In the WSVI platform, the magneto-rheological （MR） damping technique was adopted and utilized. The proposed WSVIP and the satellite model were designed and manufactured, and then the WSVI system was assembled. The tests of WSVI were conducted. Furthermore, the isolation performances of the WSVI system, a conventional MR damper vibration isolation platform and a conical adapter were evaluated and compared. The results showed that the passive isolation effect of the WSVI system is significantly better than that of the conical adapter; high-frequency decoupled MR dampers in the WSVI system can help the vibration isolation platform to reduce high frequency transmission rate and improve high frequency vibration isolation performance.
