摘　　要：在大功率电磁继电器的各种失效模式之中,焊接飞溅金属多余物引起的失效一直以来占有很高的比例,焊接飞溅金属多余物会导致产生触点间短路或击穿等失效模式。针对大功率电磁继电器的典型组件轭铁组在实际焊接生产过程中存在点焊强度差、易产生严重飞溅金属多余物等焊接质量问题,采用计算机仿真分析的方法,对大功率电磁继电器轭铁组的电阻点焊过程进行数值模拟分析。通过改进焊接结构、优化工艺参数等方法,解决了大功率电磁继电器的轭铁组焊接飞溅金属多余物较多的问题,提升了大功率电磁继电器的可靠性、稳定性。Among all failure modes of high-power electromagnetic relays,the one caused by splashing of welding take a relatively high portion.The splashing may cause short circuit and electrical breakdown between contactor.In actual situation,the yoke iron assembly tend to lack of spot welding strength and severely splash metal remains.To solve this problem,simulation of the yoke iron assembly spot welding process is used in this work.Welding structure improvement and processing parameter optimization are used to solve problem of splashing.In general,the reliability and stability of high-power electromagnetic relays are enhanced.
