摘要：提出了船舶荣油机健康状态的综合定量评估指标一健康度，用层次分析法（AHP)建立了柴油机健康评估的模型，确定影响柴油机健康状态的各评估内容及其权重系数。对于可量化的监测数据通过试验数据的拟合和无量纲化处理来获得评估健康值，对于非量化的程度描述则根据专家系统直接评估健康值，加权分析计算后可得荣油机各分系统的健康度，再以加权的方法最终确定柴油机整体健康等级。实现柴油机运行状态的实时监测评估，为柴油机的维护提供依据。关键词：船舶柴油机：评估系统；健康度；层次分析法

(School of Energy and Power, Jiangsu University of Science and Technology, Jiangsu Zhenjiang 212003) Abstract: The concept of health degree was defined, which was used as a quantitative index to evaluate the health condition of ship diesel engine. The analytic hierarchy process ( AHP) method was used to es-tablish the performance assessment model, and to analyze and determine each factor and weight coeffi cient affecting diesel engines' performance conditions. For monitoring data that can be quantified, the health state could be obtained by experimental data fitting and dimensionless processing; while for non-quantitative degree description, the health value can be directly evaluated according to the expert system, and using weighted analysis and calculation to determine the health value of the subsystems of the diesel, then the level of the whole diesel' s health condition is finally confirmed by the weighted method. With all methods mentioned above, the real-time assessment of the state of diesel engine was realized, which could provide a scientific basis for maintenance and management of diesel engines.
Keywords: marine diesel engine; evaluation system; health degree; analytic hierarchy process
0引言
船舶柴油机作为船舶的主要动力装置，其性能的好坏直接影响着船舶在海上的安全航行。因此，有效地评价柴油机的健康状态，并针对其健康状态采取适当的措施，对于保证柴油机正常运行，降低故障的发生是十分有必要的。
本文以16PA6柴油机为研究对象，通过层次分析法将柴油机系统划分成不同的评估层次，经过对试验数据的融合和无量纲化处理获得底层单因素的健康度，再以加权计算的方式逐层计算得到柴油机的健康度，在此基础上建立柴油机健康评价体系，为柴油机的养护维修工作提供依据，确保在其使用周期内安全运行。
