主要介绍了基于等代设计法的复合材料风力机叶片初始铺层设计,总结了叶片各剖面厚度计算方法;基于Matlab与ANSYS交互机制,建立了以单层层合板厚度为参数变量,使叶片总质量达到最小为目标的优化模型,分别采用遗传算法(SGA)及改进遗传算法(ASGA)对叶片结构进行优化。与ANSYS自带优化算法进行比较,叶片重量明显降低,收敛效果明显,体现了ASGA算法的优越性,为后续结构优化方法提供参考。
This paper mainly introduces the design of the initial layer of composite wind turbine blades based on the equivalent design method and the method of calculating the thickness of each section of the blade. Based on the interaction between Matlab and ANSYS, The optimization model with the goal of minimizing the mass and the optimization of the blade structure by genetic algorithm (SGA) and modified genetic algorithm (ASGA) respectively. Compared with ANSYS own optimization algorithm, the blade weight is obviously reduced and the convergence effect is obvious, which shows the superiority of ASGA algorithm and provides a reference for the subsequent structural optimization methods.
