摘 要:
本文主要是研究柴油机的健康及运行监测系统(HUMS),并以连杆铜套磨损为例进行分析。利用基于神经网络和小波分析的故障诊断方法进行健康状况的定量识别。实验和仿真结果表明:对于各设定工况,诊断模型可以定量的识别出来,准确率达到100%;对于待定工况,诊断模型也可以给出定量的健康状况描述。从而使操作者能及时地了解柴油机的健康状况,并根据定量的输出结果对相应部件进行维护。[著者文摘]

THE RESEARCH OF HUMS FOR DIESEL ENGINE BASED ON THE VIBRATION SIGNALS
HUANG Qiang; LIU Xin (Faculty of Mechanical Engineering, Jiujiang University, Jiujiang, Jiangxi 332005 )
Abstract:
In the paper, the health and usage monitoring system (HUMS) of diesel engine was proposed taken example of faults of the bushing of connecting rods. The fault diagnosis method based on the neural networks and wavelet analysis was used to identify different health degrees. According to the experiment and simulation result, for the setting sta- tus, diagnosis model could identify different grades quantificationally and accurately. For the pending status, the model also could describe the quantificational health degree. So the operator could know the health of diesel engine in time and maintain the relevant parts by the output of network model.[著者文摘]
