Optimal design of wind turbine's main shaft based on response-surface analysis
Since the high MW wind turbine with heavy weight is likely to cause hidden danger and failure,this article focu-ses on the wind turbine's spindle;the parametric modeling is carried out to set up the related.finite-element model;the analysis is conducted on the spindle's strength and stiffness according to the limited working condition.Based on the Spearman-Rank cor-relation coefficient,the DOE experimental design is carried out to obtain the sensitivity map between the spindle's size parame-ters,and five parameters of structural size that have a great impact on the spindle's performance are identified.At last,the re-sponse-surface analysis is conducted on the five parameters of structural size;with the help of the MOGA algorithm,and the best optimization scheme is worked out.The results show that compared with the original model,the optimized model reduces the spin-dle system's weight by 6.28％,and the spindle's strength and stiffness meet the design requirements,which provides theoretical support and reference for the optimization design of the wind turbine's spindle in the future.
