摘要
探讨了如何运用铁谱分析技术对东风4型机车柴油机状态进行诊断,并对柴油机中常见的几种故障以及它们对应的铁谱磨粒进行了研究。为解决铁谱定量化研究问题,采用线性回归方法和模糊数学中的综合评价方法、模糊聚类法三种方法,对柴油机磨损趋势,柴油机故障诊断进行了研究。
Researches into the state diagnostic problems of Dongfeng4 locomotive diesel by using ferrography analysis technology. Investigates several diesel troubles which are often met, and studies the wear patticals on the ferrography. In order to resolve the problems in the quantitative analysis of ferrography, three methods have been used. They are linear regression method and two fuzzy methods——multicriteria method and classification method. Studies the wear trend and fault diagnosis of diesel.
