摘　　要：高速电磁阀的关键结构参数对高压共轨喷油器的响应特性具有决定性影响,采用多目标模拟退火优化算法MOSA(Multi Objective Simulated Annealing),基于多目标多学科优化平台modeFrontier,并集成有限元分析软件Ansys,以高速电磁阀开启、关闭延迟时间和电磁力为目标函数建立了多目标优化模型,对高速电磁阀的关键结构参数进行多目标优化设计。结果表明:电磁阀开启延迟时间降低了15.4%,达到0.11 ms;关闭延迟时间降低了25%,达到0.18 ms,;电磁力提高了12.5%,达到160 N。The key structural parameters of high-speed solenoid has crucial influence on high-pressure common rail injector re- sponse. With the MOSA （multi-objective simulated annealing） algorithm, the multi-objective optimization model, which took the delay of solenoid opening and closing and the electromagnetic force as objective functions, was built based on the mode- FRONTIER multi-.objeetive multidisciplinary optimization platform that was integrated with ANSYS finite element analysis software. With the model, the key parameters of high-speed solenoid were optimized. The results show that the delay of sole- noid opening is 0.11 ms, which reduces by 15.4%. The delay of solenoid closing is 0.18 ms, which reduces by 25%. Besides, the electromagnetic force is 160 N, which increases by 12.5%.
