摘要

针对齿轮故障造成的风电机组传动系统输出响应不稳定问题,对故障状态下的传动系统动态性能进行了研究。通过考虑斜齿轮时变啮合刚度和齿轮裂纹等因素的影响作用,分别建立正常状态和齿轮故障状态下的传动系统动力学模型,对比分析了两种状态下系统的输出响应。结果显示,齿轮故障状态下,输出啮合力、扭转振动位移和扭转振动速度均相对较大,且呈现出不规则的变化趋势,在某些仿真时间点处出现较大的冲击振动。研究结果可为风电机组传动系统故障诊断及早期故障预测提供理论参考。

Abstract

Because of the output response of the wind turbine transmission system caused by the gear fault is not stable,the dynamic performance of the transmission system in fault state is studied. The transmission system dynamics models under normal condition and gear fault condition are established respectively by considering the influence of time-vary stiffness and gear crack of helical gear,and the output responses of two systems are analyzed and compared. The results show that the output engaging force,torsional vibration displacement and torsional vibration velocity are relatively large and the irregular change trends are presented under the fault gear condition. The impact vibration is large at some simulation time points. The theoretical reference for the fault diagnosis and early fault prediction of the wind turbine transmission system is provided by the research results.
