摘要
电磁系统是电磁继电器的重要组成部分。针对电磁系统计算速度与准确性相矛盾的问题,综合磁路法的快速性和有限元法的准确性优点,提出一种用于电磁继电器动态特性计算的算法。该算法能够实现电磁系统尺寸参数变化后的继电器动态特性快速计算。在与有限元法计算结果对比、验证该方法计算结果准确性的基础上,采用遗传算法,以电磁系统几何尺寸为优化变量,以增大吸合过程触点分断速度、减小触点闭合速度为目标,对电磁继电器动态特性进行优化,并给出了优化结果。
Electromagnetic system （EMS） is the important part of electromagnetic relay （EMR）. Considering the contradiction of efficiency and accuracy of solving EMS, a method integrating advantages of magnetic equivalent circuit （MEC） method and finite element method （FEM） was presented to quickly calculate the dynamic characteristics of EMR. The fast calculation of dynamic characteristics of EMR could be accomplished by this method, when dimension parameters of EMS varied. The accuracy of solutions using the proposed method was verified by comparing with the results of FEM. Moreover, adopting geometry dimensions as design variables, taking increasing the contacts＇ breaking velocity and decreasing closing velocity as goals, the EMS was optimized by genetic algorithm （GA）, and the optimized results were finally given.
