摘要
塔顶法兰疲劳强度和寿命对大型风力发电机的安全运行有重要影响,法兰关键部位应力集中因数则是影响法兰疲劳强度的关键因素。基于大型风力发电机组塔顶法兰受力理论,结合有限元分析方法,对某大型风力发电机组塔架塔顶法兰应力集中因数进行分析,为实际工程提供指导。
The fatigue strength and life span of the top flange have a significant impact on the safe operation of large wind turbines. The stress concentration factor at the vital area of the flange is the key factor that affects the fatigue strength of the flange. Based on the stress theory of top flange of a large wind turbine and in combination of the finite element analysis, the stress concentration factor at the top flange of a large wind turbine was analyzed to provide guidance for practical engineering.
