基于损伤力学理论,针对光伏组件的结构特点,建立在等幅循环荷载作用下光伏组件晶体硅电池的疲劳损伤演化模型,并与实验结果进行比较,结果表明,该模型能较好地描述组件电池片的损伤演化,即:损伤的累积是非线性的,在循环荷载作用初期电池片的损伤有一个快速发展过程,随着循环次数的增加,损伤的增速变缓。 Based on the damage mechanics theory, aiming at the structural characteristics of PV modules, the fatigue damage evolution model of PV modules based on cyclic loading under constant amplitude is established and compared with the experimental results. The results show that this model can describe the components’ The damage evolution of the patch, that is, the cumulative damage is non-linear. The damage of the patch during the initial stage of cyclic loading has a rapid development. With the increase of the number of cycles, the damage growth slows down.
