摘　　要：本文通过磁悬浮实验装置,分析了磁悬浮力的两种理论算法,比较了这两种算法的误差并与实验结果做了对比,用软件仿真计算了单匝线圈等效模型的磁悬浮力的频变特性并与理论值对比。本文在此基础上提出了多匝线圈的等效建模方法。验证表明这种方法与实验结果更接近,能比较精确地计算出盘状线圈的受力情况。Through the experiment of the magnetic levitaition,this paper analyzes two theoretical algorithm of the magnetic levitation forces,and compares the error of two algorithms with eachother,then they both compared with the test results. The magnetic force changed with frequency of the model with single turn coil is simulated with software,on this basis,the simulation model with multi turn coil is put forward. The results calculated with that model are more closed with the experiment data,the force effected on the coil plate can be calculated accurately.
