| description | Under the action of electromagnetic force, mechanical force and gravity, the radial deformation of rotor supporting must meet the design standard while ensuring the lightest mass. At first, the mathematical model of single objective optimization is established. Then, the objective function is optimized by the combination of genetic algorithm and finite element method GA-FEM . With the help of this method, the optimal design parameters of the rotor supporting are obtained. This paper takes the actual rotor supporting of 7MW prototype as the optimization object. The optimal solution of this structure without the lightweight holes can be obtained by first optimization. And then, the optimal solution of the final structure with the lightweight holes is obtained by the second optimization. The final simulation shows that the stiffness can be met while reducing the mass by 40%. |
