摘要
本文论述交流接触器电磁系统在启动过程中动态特性的有限元分析,这是属于电磁场与暂态电路和机械运动的耦合问题.本文采用参数耦合的方法求解动态联立方程组.这一方法已应用于32安交流接触器典型样机电磁系统设计.
This paper deals with the finite element analysis of the dynamic characteristics for the electromagnet of a.c.contactor during its starting process.This is a coupled problem of etectromagnetic fields,transient circuits and mechanical movement.In this paper parameter coupled method is adopted to resolve the dynamic simultaneous differential equations.This method is applied to design the electromagnet of the typical sample set of 32A a.c.contactor.
