摘　　要：为了改善ABS电磁阀的动态特性,缩短其动作时间,并考虑在制动过程中变化的油压对电磁阀运动的影响,该文利用AMESim软件建立了ABS制动系统中液压系统的模型。通过ABS混合仿真试验台实测阶梯形变化的制动压力,与同条件下的仿真结果进行对比,二者的平均差小于84000Pa。运用Optimization工具,以电磁阀动作时间为目标参数,利用遗传算法对加压阀和减压阀主要参数进行优化计算,使其动作时间分别缩短1.1ms和1.4ms。该研究对于电磁阀的优化设计和改进具有参考作用。For improving the dynamic characteristics of the ABS（anti-lock braking system） solenoid valves,reducing the moving time and considering the influence of the hydraulic pressure in the braking process,the model of ABS hydraulic system was built by using AMESim software. Step-shaped braking pressure was measured by the ABS mixed simulation test-bed,and compared with the simulated results,which showed that the mean difference was less than 84 000 Pa. Taking advantage of the tool optimization and setting the operating time of the solenoid valves as the target,solenoid valve of main parameters were optimized through the genetic algorithms,and operation time was 1.1 ms and 1.4 ms faster than before for the pressure valves and pressure reducing valves,respectively. The results that can provide reference for design and improvement of solenoid valve.
