摘要

建立风力机组齿轮传动系统的三维模型,利用ADAMS的模拟信号和实验信号对比分析,分别研究了不同转速时定轴齿轮断齿的单一故障及定轴齿轮齿根裂纹-行星齿轮断齿耦合故障,对传动系统上不同测点的影响。定轴齿轮断齿对各测点影响明显且频域分布特征基本一致,转速的变化不影响频域的分布,在高速级啮合频率、中速级啮合频率及2倍频附近有较强边频带;耦合故障时定轴齿轮裂纹对各测点高频区影响明显,行星轮断齿对故障源附近低频区影响明显,行星轮故障特征为啮合频率及其2、3倍频振幅明显,且存在明显边频;角加速度信号与实验信号主要特征频率分布基本吻合。

Abstract

The 3D finite element model of gear transmission system of wind turbine is established. Combining experimental signal and analog signal on ADAMS,the effect of the fault which based on a single failure with gear tooth broken of fixed axis and coupling faults with crack tooth on fixed axis gear- planetary gear tooth broken on different points of transmission system is studied. The fixed axis gear with tooth broken have significant impact on each measure point and have the same frequency distribution characteristic. The changes of the speed does not affect the distribution of characteristic on frequency domain. The side frequency will appear at high- level mesh frequency and the medium speed level mesh frequency and the doubler. When the gear with coupling fault,the affect of fixed axis gear crack on the high frequency area of each measure point is obvious,the affect of planetary gear tooth broken on the low frequency area near the fault source is obvious,the amplitudes of mesh frequency and multiplier frequency of planet gear and the side frequency are obvious. The angular acceleration signal and experimental signal have the same distribution of characteristics.
