摘　　要：对一种双稳态微机械电磁继电器的闭合碰撞特性进行动力学分析,根据该继电器机械系统的特点建立了碰撞模型,分析了继电器碰撞时间,并讨论了理论和测试结果。结果表明,碰撞时间可分为固定不变的碰撞闭合时间和不断衰减的碰撞断开时间,前者与继电器的系统阻尼有一一对应的关系,利用该关系可对继电器的阻尼进行测量。The contact collision characteristics dynamic analysis of a bistable MEMS electromagnetic relay was done.According to characteristics of the relay s mechanical system,the relay s collision time was analyzed,and theory and test result were discussed.The result shows that collision time can be classified fixed contact time and decreasing non-contact time.The former has corresponding relation with the relay s system damp.With the relation the damp property can be measured.
