摘要
风力机疲劳载荷的统计分析是风力机设计的基础。在模拟了十分钟紊流风速时程以及叶片根部的挥舞力矩和摆振力矩的基础上,应用雨流计数法对叶片根部载荷进行雨流计数;采用三参数Weibull分布模型,结合雨流统计进行了疲劳载荷的统计分析,得到了短期载荷分布,研究成果为风力机疲劳可靠性设计奠定了基础。
The statistical analysis of the wind turbine fatigue load is the basis for the design of wind turbine. Simulation of turbulent wind speed time ten minutes, and the root of the blade wielding torque and torque shimmy on the basis of the application ofrainflow counting rainflow counting of the blade root loads; using the three-parameter Weibull distribution mod- el, combined with the rain-fow statistics the statistical analysis of the fatigue load, short-term load distribution, research laid the foundation for a wind turbine fatigue reliability design.
