摘　　要：针对含永磁电磁结构非线性强、求解精度低等特点,提出了一种快速计算方法,即基于响应面方法得到基函数,并采用克里金方法修正实测值与计算值之间的误差,实现电磁机构的快速精确计算。在此基础上,引进分布式协同策略使快速计算可并行化执行提高效率,同时改进粒子更新策略,增强多目标粒子群算法在求解含永磁电磁结构优化问题时的鲁棒性。以含有双磁钢的电磁结构为例,使用快速计算方法进行优化设计,验证了方法的有效性。A fast calculation method was proposed that aims at electromagnetic devices with permanent magnet( PM) characteristics of strong non-linearity,low solving precision. The response surface method was used to derive the basis function,and the error between actual measured values and calculated values was modified by the Kriging method. On the basis of the calculation model,the distributed collaborative strategy was adopted to fulfill the parallel execution of the fast computation. Simultaneously,the updating strategy of particles was improved,and the robustness of the multi-objective particle swarm optimization algorithm in solving the optimization problem of electromagnetic devices with PM was enhanced. Effectiveness of the method proposed in this paper was verified by the case study of a specific type of electromagnetic relay with PM.
