基于正交试验的风电机组塔架结构参数的优化设计

摘要

本文采用正交试验设计方法设计正交试验模型，利用ANSYS有限元分析软件对正交试验模型进行静强度、疲劳强度、模态和屈曲分析，运用数据统计分析软件进行多元线性回归分析，建立优化数学模型，再应用MATLAB优化工具箱对模型进行求解，得到了塔架结构优化结果。%This paper used orthogonal experimental design method to design orthogonal test model and ANSYS FEA software to analyze the orthogonal experimental model on static strength, fatigue, modal and buckling. It also applied Statistical Analysis Software to establish a tower structure optimization mathematical model, and utilized MATLAB optimization toolbox to analyze the model and obtain the result of tower structure optimization.
