可调速异步盘式磁力联轴器的多目标优化设计

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。

Multi-objective Optimization Design of Axial Permanent Magnet Couplings With Adjustable Speed System

A mathematic model of axial permanent magnet couplings with adjustable speed systemis is established based on the linearised layer model,which takes a variety of structural parameters and performance parameters(such as thickness of permanent magnets,air gap,etc.) as design variables and takes the minimum cost and maximum torque as double optimization goals .Firstly the double objective functions are transformed into a single objective function by membership functions and linear weighing models,then the mult...
