摘　　要：针对实心盘式永磁涡流耦合器性能优化问题中参数烦杂多样及优化效率低的问题,运用量纲分析法推导盘式永磁涡流耦合器的无量纲参数,得到速度参数、磁密参数、气隙参数及主要尺寸无量纲数等6个无量纲参数,有效地减少了分析研究的工作量;通过方程分析法验证了无量纲数的正确性;运用三维有限元仿真,分析了各无量纲数对永磁涡流耦合器的输出转矩影响。为提高优化效率,通过响应面法进行了结构优化设计,以提高永磁体利用率,仿真结果验证了优化的有效性。In light of the problem of complex and diverse parameters and low optimization efficiency in the performance optimization of a solid disk permanent magnet eddy-current coupler,the dimensionless parameters of the disk permanent magnet eddy-current coupler were derived according to the dimensional analysis method.Six dimensionless parameters such as velocity parameter,magnetic density parameter,air gap parameter and dimensionless number of main dimensions were obtained,which effectively reduced the workload of the analytical study;the correctness of dimensionless numbers was verified by the equation analysis method.The impact of each dimensionless number on the output torque of the permanent magnet eddy-current coupler was simulated by the 3D finite element.In order to improve the optimization efficiency,the structural optimization design was carried out by the response surface method to improve the utilization of permanent magnets,and the simulation results verified the effectiveness of the optimization.
