机车柴油机常见故障的计算机综合诊断的研究

The technology of synthetical fault diagnois of locomotive diesel engine

在试验研究的基础上，进一步研究各常见故障的故障机理，并选择恰当的牲参数把多元分析技术与模式识别和模糊数学理论有机地结合起来，提出了“机车柴油机故障诊断的模糊多元判别法”；还建立了铁谱数据库，编制了铁谱监控程序。最后，在计算机上实现了利用振动和铁谱技术的综合诊断系统，得到满意的结果。

Based on the test research, this paper discusses the mechanism of common faults; Choose the proper characteristic parameters; integrates the fuzzy mathematics and the multivariate analysis with the model recognition theory. It also gives the monitor program by using ferrography database.
