摘要
文中设计了一套风电齿轮箱的故障分析和诊断方法,采用小波分析法对所收集的信号进行时域、频域和时频数据分析,参考风电齿轮箱的主要故障及其振动信号特征,通过对比,做出故障类型判断。一定程度上避免了因故障带来的经济损失。
This paper designs a set of wind power gear box fault analysis and diagnosis method, using wavelet analysis method in time domain for the collected signal, frequency domain analysis and time frequency data characteristics, main fault reference wind turbine gearbox extremely vibration signal by contrast, make the fault type judgment. A certain degree it avoid to due to the fault types of economic loss.
