Description: 提出了一种基于复解析小波变换的相位诊断齿轮故障的方法。复解析小波变换将Hilbert变换与小波分析紧密结合在一起,具有自适应分析能力。利用复解析小波变换得到齿轮振动信号的相位,其功率谱图上可提取调制边频带结构来识别故障模式。试验结果表明这种方法可有效应用于齿轮局部故障诊断中。-A new method using the phase based on complex analytical wavelet transform for fault diagnosis of gears was proposed. The phase of vibration signals of gears is got by complex analytical wavelet transform, which combines Hilbert transform with wavelet transform tightly and possesses adaptive analysis ability. By making spectrum analysis of the phase, the sideband structure in power spectrum can be protruded, and the fault pattern can be identified. Experimental results show that the proposed method is effective in local defect detection of gears. Platform: |

Description: This paper describes a method for detecting faults
in the tap selector by means of vibration measurements during tap
changer operation, using envelope analysis based on Hilbert transform
and wavelet decomposition. Different failures at the tap selector
can be distinguished in the vibration signature as they are
reflected in different parts of that signature. The diagnosis parameters
allowing the most selective failure classification are found. Platform: |
