摘要:

为准确评估风电齿轮在服役工况下的疲劳损伤,提出一种融合环境随机性与载荷时序性的预测框架,利用非线性损伤修正模型计算并分析了不同风速对齿轮疲劳损伤的影响规律。结果表明,低风速段的齿轮弯曲疲劳损伤由高频低幅循环应力主导,极端载荷累积显著加剧高风速段的齿轮接触疲劳,额定风速区间是造成齿轮疲劳损伤的主要风险区间。基于损伤分析结果提出了定量转速控制策略以延长齿轮箱服役寿命,为齿轮箱可靠性设计及风机轮毂转速控制提供了依据。

Abstract:

To accurately assess the fatigue damage of wind turbine gears under operational conditions, a prediction framework that integrated environmental randomness and load temporal characteristics was proposed. A nonlinear damage correction model was utilized to calculate and analyze the influences of different wind speeds on the fatigue damage of gears. The results indicate that the bending fatigue damage of gears in the low wind speed range is dominated by high-frequency low-amplitude cyclic stresses, while the contact fatigue of gears in the high wind speed range is significantly exacerbated by extreme loads accumulation. The rated wind speed range is identified as the main risk interval for gear fatigue damages. Based on the damage analysis results, a quantitative speed control strategy was proposed to extend the service life of the gearbox, providing a basis for the reliability design of the gearbox and the control of the wind turbine hub speed.
