摘　　要：通过对不同情况下电磁线圈的感应电动势和动态阻抗的分析,得到了因励磁电流和动态间隙而产生的感应电流的表达式,并对其合理性进行了分析.将动态电磁关系应用到电磁支撑装置中,得到了不同情况下电磁支撑装置的附加支撑刚度参数和附加阻尼参数的表达式,从而合理地解释了在参数识别实验中电磁支撑装置存在附加阻尼参数的现象.Based on the analysis of the induced electromotive force and the electromagnetic coil dynamic impedance of electromagnetic coil under different working conditions, the expression for induced current because of excitation current and dynamic gap was obtained, and the dynamic relationship to the electromagnetic support device, its reasonableness was the expression for its also analyzed. By using additional support stiffness parameters and additional damping parameters was obtained under different working conditions. Then the phenomenon of additional damping parameters in the parameter identification experiment of the magnetic support device was expelained reasonably.
