故障预测与健康管理在舰用柴油机中的应用

为解决舰用柴油机传统事后维修和计划维修的诊断能力不足、经济可承受能力差等问题,应用故障预测与健康管理(prognostics and health management,PHM)的理念进行研究。在分析柴油机常见故障的基础上,建立舰用柴油机动力装置的PHM体系结构,对其中主要功能模块进行分析,提出PHM在舰用柴油机中应用尚需解决的问题。该研究为实现舰用柴油机的健康管理奠定了理论基础,对现有装备的维修保障和预研装备的设计开发具有一定参考价值和指导意义。

Application of Prognostics and Health Management in Marine Diesel Engine

Prognostics and health management （PHM） was presented to solve the problems of predetermined maintenance and corrective maintenance such as insufficient diagnostic capacity and poor economic affordability of marine diesel engine. In the paper, the common faults of diesel engine are analyzed, the PHM system structure of marine diesel engine was set up, and the main functional modules are analyzed. Finally, the problems of PHM in marine diesel engine in the application were put forwards. The study provides a theoretical basis for the realization of marine diesel engine health management, and it provides reference value and direction to the repair guarantee of the existing equipment and design of advanced equipment.
