摘　　要：对电磁铁吸合和释放过程作了详细探讨,建立了高速电磁铁的电、磁、机耦合动态数学模型,导出动态力的增量方程并进行分析,指出动态特性可由静态特性间接分析获得。在不同结构参数下,对圆锥形和平面形磁极高速电磁铁进行实验和仿真,对比两者动态特性获得适用范围,研究结果为高速电磁铁的工程设计提供了参考依据。This paper explored dynamic characteristics of high-speed solenoids considering both attraction and release processes,while the present research was generally limited to the attraction process.An electric-magnet-mechanic coupling dynamic mathematic model of high-speed solenoids was established,and an incremental equation for the dynamic force was derived and analyzed which proved that the dynamic characteristics could be obtained indirectly from the static characteristics.Experiments and simulations of conical pole and planar pole high-speed solenoids were carried out with varied structural parameters respectively.And the comparison of dynamic characteristics of two solenoids indicates their suitable application ranges.The research results provide an effective reference for engineering design of high-speed solenoid.
