摘　　要：针对电磁接触器吸合时间难以手工计算的问题,通过等效惯性的概念,将Adams和Maxwell软件结合起来,实现电磁机构的瞬态仿真,计算出铁芯式衔铁电磁接触器的吸合时间,为产品开发提供了有效的参考依据。该方法同样适合于杠杆式衔铁电磁接触器吸合时间的计算。As for the problem that it is difficult to calculate electromagnetic contactor pickup time by hand,use the con- cept of equivalent inertia to combine Adams and Max well softwares to achieve the transient simulation of the electromag- netic mechanism. Calculate the pickup time of the electromagnetic contactor of the iron-core armature. It will give an ef- fective reference basis for product development. The method is also suitable for electronmagnetic contactor pickup time of the lever-type armature.
