Abstract: Aiming at the problem that the single goal optimization design could not meet the design requirements of magnetic coupling of magnetic driving pump ,Design Xplorer optimization design module and Ansoft Maxwell 14.0 finite element analysis module on ANSYS Workbench were used by multiobjective optimization design of magnetic coupling of magnetic driving pump. The initial reference design parameters were obtained by method of semitheoretical and semiempirical. The costeffective parameters of magnetic coupling were obtained based on central composite design method and optimization algorithm NSGAII. The results show that the optimized target index Tmax / v is about 7 % higher than that of the initial parameters, and the Pw is about 9 % less than that of the initial parameters .The simulation results indicate that the optimized parameters can reduce production cost and energy consumption of magnetic coupling and meet design requirement.
