摘　　要：由于微机电系统(MEMS)技术的迅猛发展,以此为基础的微电磁继电器的应用前景也越来越广阔。为使微电磁继电器的结构进一步优化,基于已有的微电磁继电器的研究,提出了微电磁继电器的结构模型并建立了相应的仿真模型,通过ANSYS有限元模拟软件,对微电磁继电器的关键组成部分平面磁芯线圈所产生的电磁场的分布和活动电极(衔铁)在线圈电磁感应产生的电磁场中所受电磁力情况进行仿真计算,以及受力应变进行分析,得到影响微电磁继电器结构设计的重要考虑因素,比如电流激励、活动间隙等,总结出结构设计依据,对未来微电磁继电器结构的进一步优化具有一定的参考意义。Due to the rapid development of microelectromechanical system(MEMS) technology, the application prospects of microelectromagnetic relays based on this are also becoming more and more broad. In order to further optimize the structure of the micro-electromagnetic relay, a structural model of the micro-electromagnetic relay was proposed based on the existing research on it, and a correspon-ding simulation model was established. The distribution of the electromagnetic field generated by the plane magnetic core coil, a key component of the micro-electromagnetic relay, and the electromagnetic force acted on the active electrode(armature) in the electromagnetic field generated by the electromagnetic induction of the coil were simulated and calculated. The force strain was also analyzed. The analysis obtains important considerations affecting the structural design of micro-electromagnetic relays, such as current excitation and free play, etc., and summarizes structural design principles, which have certain reference significance for further optimization of the structure of micro-electromagnetic relays in the future.
