| 摘 要： | 以某型蒸汽船的主冷凝器水位调节器为研究对象,应用卷积型小波包变换提取各种故障信号分解后的相对小波包能量,建立水位调节器标准故障库,并引进Euclidean空间距离公式作为判据进行故障识别。实验结果表明,该方法可以对水位调节器的典型故障进行快速、正确分类,降低了其故障定位与维修的盲目性。

| Abstract: | Based on the research on water level regulator of steam-power ship's main condenser,this paper picked up the relative energy eigenvector by using the convolution type of wavelet packet decomposition,built the standard fault database,and took Euclidean space range formula as criterion to identify faults. The experimental results show that this method can diagnose the typical faults of the water level regulator quickly and correctly. And this method can also decrease the blindness of the diagnosis and the mai... |
