Abstract

In order to realize the lightweight design for main shaft of wind turbine, Firstly, according to the finite element results, a mathematical model was established with mass as objective function, stress and deformation as constraint conditions. Then the method of Design of Experiment （DOE） was used to obtain the initial sample points, and the Kriging model was used to establish the response surface, obtain influence degree and variation trend of each design variable on stress, deformation and quality, at the same time, get the local optimal solution. Finally, the Multi Objective Genetic Algorithm （MOGA） was used for optimization, and the global optimal solution was obtained thought 1100 iterations. The weight of the main shaft was reduced by 10.71%, which provided a reference optimization design method for the lightweight design of other parts of the wind turbine.
