| 摘 要： | 根据风力发电机叶片的实际铺层和使用状况,以刚度退化模型为基础,发展了一个适合于风力发电机叶片的损伤演化模型,模型的基本思路是以单层板的刚度退化规律来预测整个叶片的损伤演化过程.对损伤过程进行了分析,给出了复合材料层合板刚度退化、内部损伤和损伤累积规律.

| Abstract: | To predict the damage evolution of wind turbine blades,a new model based on stiffness degeneration is developed,the model consider the actual ply scheme and working condition of blades,predict blade damage by the rules of stiffness degeneration in each layer. Through analysis the damage process,the stiffness reduction of laminates is given,the fatigue damage and cumulative fatigue damage rules are defined. |
