航天电磁继电器是一种广泛应用于航空航天、武器装备等领域的电器元件,其触点的滑移可以去除触头表面的氧化膜,分离起弧点与工作点.触点滑移长度的研究有利于提高触点接触可靠性及继电器产品寿命,本文通过对簧片与触点结构建模,得到了触点切向角及接触角变化量计算方程;通过建立接触系统的柔度、装配尺寸链计算方程确定了触点滑移长度.以触点结构参数为变量,采用均匀设计方法得到了触点滑移长度的多元线性回归模型,并确定了最优的结构参数.

Space electromagnetic relay has been widely used in aerospace and weapon equipment fields. The slip of the relay contact can remove the oxide film on the contact surface and separate the arcing point from operation point. So, the study on contact slip length will help to improve the reliability of the contact and the lifespan of the space relay. In this paper, the variable calculation equations of tangential angle and contact angle are established based on structural modeling of the reed and the contact. Through establishing the flexibility and the assembly dimension chain equations of contact system, the contact slip length is determined. Taking the contact structural parameters as variables, multiple linear regression model of the contact slip length is established by uniform design method, and the optimal structural parameters are also decided.
