摘　　要：目前,在电磁继电器的设计和优化过程中,缺乏通过计算机仿真求得返回系数的方法。因此,提出了通过对吸合及释放过程进行动态特性仿真来计算返回系数的方法。此方法能准确地对电磁继电器的返回系数进行计算,并获得衔铁吸合和释放过程中的动作特性。应用此方法对某电磁继电器的返回系数进行仿真计算,并把仿真结果与试验结果进行对比,验证了此方法的准确性。A calculating method of return factor based on the simulation of dynamic characteristics was proposed. This method is able to calculate the return factor of electromagnetic relay accurately, and the operation characteristics of armature can also be obtained. The return factor of an electromagnetic relay was calculated by this method and the accuracy of simulation was evaluated through experiments.
