EMD分解和支持向量机技术在风电齿轮箱早期齿轮磨损故障诊断中的应用

针对目前风电机组齿轮箱故障率很高，特别是对兆瓦级风电机组齿轮箱早期齿轮故障缺乏有效诊断经验的现状，提出EMD分解和支持向量机技术方法相结合的故障诊断方法，以行星齿轮箱为试验平台，充分利用两种方法的各自优势，对风电机组齿轮箱的齿轮早期故障诊断进行研究。

Early Recognition Based on EMD and Support Vector Machine for Wind Power Gear Box Failure

The current wind turbine gear box failure rate is high,especially lack an effective early diagnosis way for the megawattclass wind turbine gear box fault.From the gear box unit and the input excitation characteristics of the internal structure, EMD and Support Vector Machine is gaved,with making full use of their advantages,can realize the early diagnosis of the wind turbine gearbox fault.
