对300 kW风力涡轮机的某些叶片中检测到的损坏进行的检查表明，这些损坏的性质可能是由于疲劳机制造成的。研究了产生失效的原因（表面裂纹、几何集中、厚度突变），并通过“德国劳氏船级社”（GL）标准的疲劳寿命简化评估程序验证了这些原因可以解释在失效发生的时间段内检测到的失效。(c)2008爱思唯尔有限公司保留所有权利。
The inspection of damages detected in some blades of 300 kW wind turbines revealed that the nature of these damages was probably due to a fatigue mechanism. The causes that had originated the failure (superficial cracks, geometric concentrator, abrupt change of thickness) have been studied, verifying, by means of the simplified evaluation procedure of fatigue life of the "Germanischer Lloyd" (GL) standard, that these causes can explain the failure detected in the period of time in which it happened.
