摘　　要：为了满足设备在不同位移下对电磁力的需求,本文以某一型号长行程直流电磁铁为研究对象,构建了电磁铁各组成部分三维模型,借助麦克斯韦方程组相关理论,结合约束条件与初始条件,搭建电磁铁三维数学模型。同时,进行电磁铁静态磁场仿真分析,获取电磁力、磁感应强度、磁力线分布特性,并通过实证研究进行验证。实验结果表明,铁心位移越小,径向气隙越小,产生漏磁越小,获得的电磁力越大,铁心在靠近底面端面时,力位移特性较好;仿真数据与实验数据具有较高的一致性,并能有效获取磁感应强度和磁感线分布特征,实现电磁场磁场可视化效果,所搭建仿真模型具备可行性。该研究为长行程电磁铁电磁力分析提供理论和实验依据。In order to meet the requirement of equipment electromagnetic force under different displacements,this paper takes a certain type of long-stroke DC electromagnet as the research object,and constructs the threedimensional model of each component of the electromagnet.Based on the related theory of Maxwell＇s equations,combining the constraints and initial conditions,it sets up three-dimensional electromagnet mathematical model.At the same time,the static magnetic field of the electromagnet is simulated and analyzed,and the electromagnetic force,magnetic flux density and magnetic flux distribution are obtained,and verified by empirical research.The experimental results show that the smaller the core displacement,the smaller the radial air gap,the smaller the MFL and the larger the obtained EMF.The force displacement characteristics of the core near the bottom face are better.Simulation data and experimental data have high consistency,and can effectively obtain the magnetic induction intensity and magnetic induction line distribution characteristics,to achieve the magnetic field visualization effect,the simulation model set up with feasibility.The research provides theoretical and experimental basis for the electromagnetic force analysis of long-stroke electromagnets.
