摘　　要：采用响应面法与有限元法结合方式,以电动机推力和铁耗作为优化目标,对双边初级永磁型游标直线(double-sided linear primary permanent magnet vernier,DSLPPMV)电动机进行了优化设计.分析了设计参数对电动机推力和铁耗的影响,进而得到高敏感度参数.针对这些参数的不同取值情况,采用有限元法,仿真计算得出各参数下的推力和铁耗.通过响应面法拟合出推力和铁耗的模型,从而得出最优设计点,即最优参数.基于方差分析证实了得到的推力和铁耗模型的准确性.通过样机加工及试验,验证了分析方法的有效性.结果表明:分析方法提高了优化效率和优化精度,优化后的电动机性能得到了提高.Combining the response surface method(RSM)with the finite element method,a double-side linear primary permanent magnet vernier(DSLPPMV)motor was optimized based on the optimization objectives of thrust force and iron loss.The influence of design parameters on motor thrust force and iron loss was analyzed to obtain the high sensitivity parameters.The thrust force and the iron loss for different parameters were calculated by the finite element method.The models of thrust force and iron loss were obtained by response surface method to obtain the optimal design point and the optimal dimension parameters.The model accuracy was verified by variance analysis,and the prototype was built to verify the analysis method by experimental test.The results show that the efficiency and accuracy are increased by the analysis method,and the motor performance is improved after optimization.
