摩擦学故障诊断技术在机车柴油机的应用

The Application of Tribology Fault Diagnostic Technique to Locomotive Diesel Engine

介绍了应用摩擦学故障诊断技术，对机车柴油机润滑系统的磨损颗粒和润滑介质分别作了光谱分析和理化性能测试。通过综合研究，能诊断出柴油机曲轴箱窜燃气的故障状态，并可确定其故障发生部位，旨在提高机车柴油机的可靠性。

In this paper, the application of the tribology fault diagnostic technique to the spectral analysis and the measurements of physical and chemical properties which are made respectively for worn-out particles and the lubricant in the lubricating system of the locomotive diescl engine is presented. The malfunctional blow-by to the engine crankcase and its actual position can be diagnosed by using the technique with intent to improve the reliability of the locomotive diesel engine.
