• Abstract Taking a 5MW wind turbine spinner as the research object and the lightest quality of the structure as target under the condition of ensuring that the comprehensive performance of the structure meets the design requirements, using the combining method of finite element analysis and multidisciplinary structural optimization, applying hierarchical optimization strategy, the optimal mathematical model were established. The lightweight design scheme of spinner was obtained by optimizing the layout of the stiffener and the laminate parameter. The structure analysis results indicate that the optimized spinner model meets the requirements in terms of comprehensive performance, while the quality is greatly reduced. This provides a method for the lightweight design of the spinner and also provides an idea for the optimization design of large composite shell structure composed of multiple parts.
