说明：  针对风力发电机齿轮箱的故障，介绍常用的故障诊断方法，理论上分析齿轮箱故障振动 信号的特征，并用 软件仿真其振动信号 对比正常运行与发生故障时的频域信号波形，并进行了一定的分析，为风力发电机齿轮箱的故障诊断提供了参考
(Wind turbine gearbox failures, to introduce fault diagnosis method theoretically analyze the characteristics of the vibration signal of a gearbox failure, software simulation of the vibration signal contrast to the normal operation and failure frequency domain signal waveform, and must analysis to provide a reference for the wind turbine gearbox fault diagnosis)
