基于热经济学结构理论的船舶柴油机系统故障诊断

Malfunction diagnosis of marine diesel engine system based on structural theory of thermo-economics

为解决船舶柴油机系统的故障诊断与定位问题,依据热经济结构理论,建立基于船舶柴油机系统物理结构和生产结构的故障诊断模型,并以"育鲲"轮柴油机能量系统为例,结合实船运行参数计算分析.仿真结果表明,该模型可以有效地对船舶柴油机系统单一故障和多故障进行诊断与定位.在此基础上,设计了一种船舶柴油机故障检测系统,该系统具有一定的实船应用价值.

To solve the problem of malfunction diagnosis and positioning of marine diesel engine system , a malfunction di-agnosis model based on physical structure and productive structure of diesel engine was established according to the structural theory of thermo-economics .Taking the diesel ener-gy system of “Yukun” as an example , the analysis was car-ried out according to the operating parameters of the real ship . Simulation results show that the model can effectively solve the diagnosis and localization of single fault and multiple faults of marine diesel engine system .On this basis, a marine diesel engine fault detection system is designed , which has a certain application value .
