摘　　要：汽车液压ABS电磁阀的动态特性对ABS的性能起着非常重要的作用。采用有限元方法 ,以ANSYS软件为平台 ,建立典型电磁阀的电磁场有限元模型 ,模型中 ,考虑了材料非线性磁特性和主工作气隙结构的影响。采用不完全乔累斯基共轭梯度 (ICCG)算法对模型进行求解 ,研究不同的线圈电流和动铁开度状态下电磁阀磁场的磁矢势和磁场强度 ,以及动铁所受的电磁力和线圈电感的动态响应特性。仿真分析结果得到了实验结果验证。Dynamic response of solenoid valve is very important to the performance of ABS Based on ANSYS, finite element analysis is used to develop a typical ABS solenoid valve model,in which magnetic flux density \%(B)\% being nonlinearly proportional to magnetic field intensity\%(H)\%and the structure of the gap are take into account The Incomplete Cholesky Conjugate Gradient(ICCG)Solver is selected to solve the system of equations As function of the coil current and plunger position,the magnetic force,coil inductance as well as magnetic flux density,magnetic field intensity and magnetic vector potential are studied The result is verified by test
