喷油泵轴系扭振的特征分析与诊断

Fault Diagnosis and Analysis of Torsional Vibration of Fuel Injection Pump Shaft

通过6135G柴油机喷油泵进行单缸停油、多缸停油等多种故障进行设置,用自制的柴油机多通道扭振仪进行扭振频谱特征分析,用神经网络进行故障智能诊断,收到良好的效果。

In this paper,by single-cylinder misfire &multi-cylinder misfire for injection pump of Model 6135G diesel engine,analysis with torsional vibrometer on fuel injection pump shaft and monitoring and diagnosis of shafting torsional vibration with neural network,a good result has been obtained.
