| 摘 要： | 电磁继电器触点的碰撞接触及所引起的回跳是影响继电器可靠性与电寿命的重要因素.传统的动态特性计算中,大多对此回避或仅作简化处理.本文提出了具有回跳特征的继电器动态反力计算模型.它通过分别建立衔铁与各触簧的动力学方程,将簧片结构等效为弹簧-振子模型,采用弹簧-阻尼模型计算连续接触力等方法得到动态反力特性.得到的动态反力特性包括触点间接触力、推杆接触力和各部件的运动速度及位移.经仿真与实验验证,使用该计算模型得到的结果是正确的.计算结果还表明,控制触点闭合速度、减小簧片刚度可以减小触点回跳、控制衔铁速度、增大动合超程及空程可以避免触点二次回跳.

| Abstract: | The collision of electromagnetic relay contacts and corresponding bounce have a strong influence on relay reliability and electrical life. However, in traditional dynamic characteristic calculations, the bounce is usually neglected or simplified. In this paper, a dynamic reaction calculation model of the relay that considers the bounce is presented. Dynamic reaction characteristics are obtained by establishing kinetic equations of armature iron and every reed, equivalent treating reed structure by mass-spri... |
