| 摘要: |
| 以2 MW风力发电机叶片为研究对象，通过Matlab中的优化函数fmincon对风机叶片的关键参数(弦长、扭角、轴向和周向因子)进行优化.采用UG建模，导入ABAQUS分析软件，将叶片分为叶片根部、主梁、前缘、后缘、腹板5个部分分区域铺层后，对其施加载荷进行静力学分析，分析不同部位应力和应变规律，同时对叶根部位的复合材料层间力进行分析.

| Abstract: |
| Here 2 MW wind turbine blade is selected as the research object.The optimization function of fmincon in Matlab is used to optimize the fan blade key parameters, including the chord length, torsion angle, axial and circumferential factors. Imported UG Modeling to ABAQUS, The blade is divided into five parts: the blade root, the main beam, the leading edge, the trailing edge, and the web. After laminated, statics analysis is performed by applying the loading. The stress and strain analysis of different parts of turbine blade suggested that blade root possesses the maximum stress and blade end possesses the maximum deformation degree. Composite interlaminar stress analysis of the blade root found that -45° layer of interlaminar stress is the largest, and stress showed cyclical changes with the laying Angle. Through the static analysis and interlaminar stress analysis of the blade, a solid basis for the blade design can be established.
