综合层次分类方法在舰船动力装置故障诊断中的应用研究

Application of Comprehensive Hierarchy Method to the Fault Diagnosis of Marine Power Plant

针对舰船动力装置结构、功能以及故障上都具有良好的层次特性,运用综合层次分类方法建立了舰船动力装置的分类层次体系。利用该方法,通过诊断将故障缩小在一定范围内,可以快速、准确地确定故障的类型和具体物理位置。

Based on the structure hierarchy, function hierarchy and fault hierarchy of marine propulsion plants, the elassified hierarchy system is established by a synthetic method, whieh divides the marine propulsion plants into several parts. With this method, the faults can be diagnosed and reduced to a small range, and then the types of faults and the idiographic physical positions can be aseertained quiekly and aeeurately.
