摘　　要：为提高大气隙外笼型转子磁力耦合器的电磁转矩,通过建立有限元模型进行仿真并分析各主要结构参数对其电磁转矩的影响,对比分析仿真结果得出影响较大的因素,进一步结合响应面优化法对其进行优化设计。通过Design Expert进行优化设计试验,拟合得到电磁转矩回归方程,求解回归方程得到最大电磁转矩时的各结构参数。通过Ansoft有限元软件进行验证,仿真结果与拟合方程预测最优值基本一致,证明得到的优化结果是准确可靠的,优化后该磁力耦合器的电磁转矩较优化前提高了18.2%。In order to improve the electromagnetic torque of the cage rotor magnetic coupler outside the large gap,the finite element model was established to simulate and analyze the influence of the main structural parameters on its electromagnetic torque.Comparing and analyzing the simulation results,the factors with greater influence are obtained,and the optimization design is further combined with the response surface optimization method.The optimization design experiment was carried out through Design Expert,the electromagnetic torque regression equation was obtained by fitting,and the structural parameters of the maximum electromagnetic torque target were obtained by solving the regression equation.Verified by Ansoft finite element software,the simulation results are basically consistent with the optimal value predicted by the fitting equation,which proves that the optimization results obtained are accurate and reliable,and the electromagnetic torque of the magnetic coupler after optimization is 18.2%higher than that before optimization.
