摘　　要：为研究不同续流策略对于接触器分闸动态特性的影响关系,建立了一种基于插值运算的智能交流接触器耦合动力学仿真系统。设计了用于二维插值计算的磁机耦合求解方法,实现了电磁力与接触器动态特性之间的耦合,避免了采用RungeKutta法对耦合模型进行数值求解,提高了程序的运算效率。基于仿真与试验系统,研究了两种不同续流方案下触头支持与动触头的碰撞力大小、分断时间、触头支持速度、加速度等动态参数,并得到最优的电磁续流控制策略。In this paper,a coupling dynamics simulation system of intelligent AC contactor based on interpolation operation was built to study the effects of different freewheeling strategies on the dynamic characteristics of contactor. The coupling solution of magnetic machine for two-dimensional interpolation calculation was designed,and the coupling between the electromagnetic force and the dynamic characteristics of the contactor was realized. It was found that this method avoids the numerical solution of the coupled model by the Runge-Kutta method,which remarkably improves the computational efficiency of the program. Based on the simulation and experiment system,the paper also studied the dynamic parameters of contact support and dynamic contact under two different flow schemes,including the size of the collision force,the breaking time,the speed of the contact,the acceleration. Finally,the optimal control strategy of electromagnetic continuous flow was obtained.
