摘　　要：以汽油缸内直喷式高压泵电磁阀为研究对象,利用FLUX软件计算分析了不同电磁阀线圈设计,如电磁阀零部件材料、电磁阀工作气隙与线圈的相对位置、线圈形状和线圈匝数等对电磁特性的影响;并在仿真计算与试验验证相结合的基础上,提出了最佳电磁特性的线圈设计,结果显示:采用优化的电磁阀材料和线圈结构能够显著提高电磁阀的电磁力,最高可达20%。The effects of the materials of solenoid valve,the position relationship between work air gap and coil,the coil shape and the coil turns on the electromagnetic characteristics were analyzed by using the software FLUX,based on the solenoid valve for high-pressure pump of gasoline direct injection system.After the analytic result is validated by the experimental test,a set of optimized coil parameters have been proposed.With the optimized coil design,the electromagnetic force significantly increases,up to 20%.
