摘　　要：针对一种具有强电磁力密度特性的高速电磁执行器开展性能优化研究。建立高速电磁执行器多物理场耦合仿真模型,通过计算得到不同参数对电磁力密度的影响规律,结合量化分析方法筛选得到3个电磁力密度的关键影响因素;采用最优拉丁超立方试验设计方法建立电磁执行器开启过程中的平均电磁力密度及总响应时间的近似模型;基于建立的近似模型构建电磁执行器性能的多目标优化模型,并采用NSGA-Ⅱ算法求解得到Pareto解集,结合最小距离法确定最优解。结果表明:优化后的电磁执行器在开启过程中的平均电磁力密度提升了14.9%,总响应时间减小了26.7%,空间利用率及动态响应特性均得到提升,研究结果可为高速电磁执行器的优化设计提供理论指导。The performance optimization of a high-speed electromagnetic actuator(HSEA)with strong electromagnetic force density is carried out.The coupled multi-physical field simulation model is established,and the influence of different parameters on the electromagnetic force density is obtained through calculations.Combined with the quantitative analysis,three key influential factors of the electromagnetic force density are selected.An approximate model of the average electromagnetic force density and the total response time during the opening of the HSEA and the total response time is established by using the optimal Latin Hypercube test design method.Based on the established approximation models,a multi-objective optimization model of the HSEA performance is developed,and the Pareto solution set is obtained by NSGA-Ⅱ.Combined with the minimum distance method,the optimal solution is determined.The results show that,after optimization,the average electromagnetic force density in the opening of the HSEA is increased by 14.9%,and the total response time is reduced by 26.7%,with improved space utilization and dynamic response characteristics.The research results can provide a theoretical guidance for the optimal design of HSEA.
