摘要
针对空间在轨环境下敏感载荷的超精密定位与振动抑制问题,提出了一种基于超磁致伸缩作动的定位、隔振一体化驱动系统方案,并以被动隔振性能为指标,进行了系统关键部件的优化;通过建立整个系统的动力学模型,进而利用Simulink搭建了系统仿真模型;通过仿真分析结合实验测试对所提方案的定位和隔振一体化性能进行了验证。结果表明:所提驱动系统具备定位和隔振一体功能,能在实现定位过程中对60Hz以上外界干扰进行被动抑制;在干扰频率为150Hz时,隔振效果可达-23.5 dB。
Aiming at the ultra-precision positioning and vibration suppression for sensitive payloads on-orbital working environment, a giant magnetostrictive driving positioning and vibration suppression system is proposed. The passive vibration isolation performance is selected as the optimization objective to realize the optimization design of the key part of the integrated system. The dynamic model of the whole system is built and the simulation model is constructed through Simulink. The simulation analysis and experimental tests are carried out to test the integrated system. The results show that the proposed integrated system realizes the ultra-precision positioning, and suppresses the vibration above 60 Hz, and the vibration suppression effect could be up to -23.5 dB in 150 Hz.
