摘　　要：文章通过建立风电齿轮传动系统扭转动力学模型,提出了基于机理模型与运行状态的风电齿轮传动系统动力学参数辨识与疲劳损伤预估方法,分析了不同齿轮磨损状态下的风电齿轮传动系统动态响应与疲劳损伤预估效果。分析结果表明:通过辨识得到的齿轮转动惯量和啮合刚度与目标值吻合较好;同一齿轮的接触疲劳损伤普遍大于弯曲疲劳损伤,且齿轮磨损会加剧动态啮合力波动,增大疲劳损伤,在不同齿轮磨损状态下,系统动态响应和齿轮疲劳损伤的预估值与目标值均吻合较好。Through establishing the torsional dynamic model of wind turbine gear transmission system,a method of dynamic parameter identification and fatigue damage prediction of wind turbine gear transmission system based on mechanism model and operating state is proposed,and the dynamic response and fatigue damage prediction effect of wind turbine gear transmission system under different gear wear states are analyzed.The research results indicate that the identified gear rotational inertia and meshing stiffness are in good agreement with the target values;The contact fatigue damage of the same gear is generally greater than that of bending fatigue damage,and gear wear can exacerbate the fluctuation of dynamic meshing force and increase fatigue damage.Under different gear wear states,the estimated values of system dynamic response and gear fatigue damage are in good agreement with the target values.
