摘要
在某型号航天电磁继电器磁系统结构的基础上,给出了吸力特性磁路计算方法,由解析法推导出工作气隙磁阻表达式。计算实例表明该方法建模速度快,应用方便,易于修改,可满足工程应用精度要求。
The magnetic circuit calculation method of attraction force characteristic is presented on the basis of an aerospace electromagnetic relay′s magnetic system structure, and the magnetic reluctance expression of working gap is deduced by analytical method. The calculated examples show this modeling method is fast, convenient, and easily modified, and meets the precision requirements of engineering applications.
