摘要
对一座失效风电塔架进行了静强度、动力学分析以及疲劳强度的设计分析,从而指出该风电塔架的失效是由于焊接结构中可能存在缺陷,同时指出风电塔架在疲劳设计中应考虑疲劳载荷的随机性和结构的缺口性。
The design analysis for static strength, dynamic analysis and fatigue strength were carried out for a failure tower structure of wind turbine. The failure cause was a existed defect in welding seam of the tower structure. The probability of fatigue load and defect of structure should be considered in fatigue design of tower structure of wind turbine.
