摘要
通过对风力发电机组叶片的运行工况进行分析和模拟计算,验证了叶片损坏的主要原因是在风力发电机组失速工况下,摆振方向的振动出现发散,叶片承受的动态载荷过大造成损坏。
In this document, the author calculated and simulated the behavior of the blades in operating and found that the main reason to result in damage of blade was the edge wise vibration during stall. In stall cases, the edge wise vibration of blade was emanative, which will lead to damage of blede.
