在对可调速异步盘式磁力联轴器引入层模型理论的基础上,以多种结构参数和性能参数(永磁体轴向厚度、气隙长度等)作为设计变量,减少材料成本和提高转矩性能为双优化目标,建立了数学优化模型。基于上述模型,建立了双目标函数各自的隶属函数,采用线性加权求和法将双目标函数转化为单目标函数;然后运用惩罚函数法把多约束问题转化为无约束问题,进而利用遗传算法对联轴器的各参数进行了优化。优化结果表明,联轴器的总体积下降了16.98%,转矩提高了12.82%,该算法具有良好的优化效果。
Based on the theory of variable layer speed disk magnetic coupling introduced layer model, with a variety of structural parameters and performance parameters (permanent magnet axial thickness, air gap length, etc.) as a design variable to reduce the cost of materials and improve turn Moment performance is the goal of double optimization, and a mathematical optimization model is established. Based on the above model, the membership function of the two-objective function is established, and the dual-objective function is transformed into the single-objective function by the linear weighted summation method. Then, the penalty function method is used to transform the multi-constraint problem into the unconstrained problem. Then, The parameters of the shaft have been optimized. The optimization results show that the total volume of the coupling decreases by 16.98% and the torque increases by 12.82%. The algorithm has a good optimization effect.
