基于LabVIEW的小波分析在船舶柴油机故障诊断中的应用

Application of Wavelet Analysis in Fault Diagnosis of Marine Diesel Engine Based on LabVIEW

测取船舶柴油机缸体振动信号。利用LabVIEW并结合小波分析对信号进行处理,提取故障特征。诊断结果与实际情况相符,说明了该方法的可行性及有效性。

The signal data of cylinder body vibration of a marine diesel engine was measured and obtained in this paper. Make use of LabVIEW combined wavelet analysis to process the signal data, the characteristics parameters were picked up to diagnose the engine faults. The result can accord with the actual circumstance, so this method is viable and valid.
