摘　　要：为了提高磁力齿轮在高速运行阶段的稳定性,根据传统磁力齿轮转矩性能研究结果,通过响应面法优化对调磁块与内外转子,提出了参数优化模型,并进行参数敏感性分析。研究结果表明:通过Box-Behnken试验设计(BBD)方法完成磁力齿轮响应面模型的样本采集,获得合适响应面模型,通过布谷鸟算法完成智能寻优,得到具备较大敏感性的优化值。根据优化结果,得到调磁块极弧系数为0.85,调磁块厚4.2 mm,内转子永磁体厚3.8 mm。经过优化处理,输出转矩由430 N·m增大到475 N·m,齿槽转矩由3.60 N·m减小至2.76 N·m。经过优化处理的真空式磁力齿轮稳态转矩从420 N·m提高到了475 N·m,优化后的齿槽转矩降低到了2.04 N·m。经过优化处理后,真空式磁力齿轮效率获得了进一步上升,同时减少了谐波含量。In order to improve the stability of magnetic gear at high speed,response surface methodology was used to optimize the magnetic switching block and internal and external rotor according to the research results of the torque performance of traditional magnetic gear.A parameter optimization model is proposed and the sensitivity analysis of parameters is carried out.The research results show that the Box-Behnken design(BBD)method is used to complete the sample collection of the response surface model of magnetic gear,and the appropriate response surface model is obtained.The Cuckoo algorithm is used to complete the intelligent optimization,and the optimal value with large sensitivity is obtained.According to the optimization results,the pole arc coefficient of the magnetic block is 0.85,the thickness of the magnetic block is 4.2 mm,and the thickness of the permanent magnet of the inner rotor is 3.8 mm.After optimization,the output torque increases from430 N·m to 475 N·m,and the cog torque decreases from 3.60 N·m to 2.76 N·m.The steady-state torque of vacuum magnetic gear is increased from 420 N·m to 475 N·m after optimized treatment.The optimized cog torque is reduced to 2.04 N·m.After optimized treatment,the efficiency of vacuum magnetic gear is further increased and the harmonic content is reduced.
