摘　　要：设计了一种磁悬浮主动隔振器,分析了隔振器的结构与工作原理。通过ANSYS有限元方法仿真计算隔振器漏磁大小,在仿真计算的基础上,采用460型三通道霍尔效应高斯计实际测量了漏磁大小,仿真计算结果与实验结果吻合。并针对隔振器的漏磁提出了优化方案,仿真计算结果表明该优化方案可行。A maglev active vibration isolator was designed;and its structure and working principle were introduced.The size of the electromagnetic force is an important index which affects maglev active vibration isolation performance,and the flux leakage is a main factor of the electromagnetic force.The analysis on the flux leakage was done by the finite element method.The magnetic field distributing of the maglev active vibration isolator was analyzed with ANSYS.On the basis of simulation model,type 460 three-channel Gaussmeter was employed to measure the actual flux leakage size.The experimental result was in good agreement with the simulation result.At last an optimization scheme which can reduce the flux leakage was proposed.And the simulation results showed that the optimal scheme was feasible.
