【摘要】 为了满足未来我国空间科学实验对高微重力环境水平的要求,需要发展高水平主动振动隔离技术来保证实验需要的高微重力水平。介绍了微重力振动隔离技术的研究现状,根据我国科学实验载荷的发展要求提出了空间高微重力主动隔振系统设计方案,建立隔振系统的动力学模型并做出了仿真分析,结果表明,线性化后的动力学模型可以用于隔振系统的主动隔振控制。更多还原

【Abstract】 The latest development of microgravity vibration isolation technology was reviewed.On the basis of introducing a magnetically levitated vibration isolation,a design frame of a high quality microgravity vibration isolation system was analyzed and a linear dynamic model was inferred.By comparing the simulation results,it was suitable for controller design instead of a non-linear model.更多还原
