对零功率磁悬浮主动隔振系统进行了理论分析和实验研究。由于零功率磁悬浮系统的行为就像它具有负刚度，将其与普通弹簧串联可以产生无穷大的刚度，以抵抗作用在隔离台上的干扰。即使在与串联组合并行地引入支撑隔离台的重量的悬架时，也保持该特性。通过对一个单轴装置的简单模型的分析，阐明了该系统的基本特性。通过测量零功率磁悬浮的力-位移特性来估计负刚度特性。实验证实，结合零功率磁悬浮与正常的弹簧产生高刚度对静态直接干扰作用在隔离表。(c)2006爱思唯尔有限公司保留所有权利。
An active vibration isolation system using zero-power magnetic suspension was studied analytically and experimentally. Since a zeropower magnetic suspension system behaves as if it has negative stiffness, connecting it in series with a normal spring can generate infinite stiffness against disturbances acting on an isolation table. This property is maintained even when a suspension that supports the weight of the isolation table is introduced in parallel with the serial combination. Analysis of a simple model involving a single-axis apparatus clarified the fundamental characteristics of the system. The force-displacement characteristics of the zero-power magnetic suspension were measured to estimate the negative stiffness properties. It was experimentally confirmed that combining a zero-power magnetic suspension with a normal spring generates high stiffness against static direct disturbances acting on an isolation table.
