船舶主推进系统是船舶的动力源，它的安全可靠是船舶能够正常航行的基本保证，也关系到财产安全和船员的生命安全，因此，目前对船舶的主推进系统的安全可靠性要求越来越高。需要快速、精确、高效的检测故障并完成维修管理，而目前传统的经验故障检修方法已经不能满足可靠性发展的要求，因此有必要采用先进的数学方法和计算机技术融合现场的经验积累对主推进系统的可靠性进行研究。
本文在探索船舶主推进系统国内外研究现状及其发展趋势的基础上，介绍了船舶主推进系统的基本结构形式，分析了主推进系统各级子系统常见的故障类型，并对故障进行了影响程度的分级。结合可靠性分析的常用方法——故障树分析方法，对主推进系统进行了可靠性分析，并以传统故障树分析为基础，以大型船用齿轮箱为例，进行了故障树可靠性仿真研究，编制了计算可靠性指标的程序，最后得到单元重要度、单元模式重要度和可靠度等可靠性参数，运用VC++与MATLAB混合编程技术，实现了对可靠度曲线的模拟输出。
在对主推进系统的维修决策方法研究中，重点介绍了各种维修方式，并对常用的决策模型进行了详细的阐述，着重介绍了灰色聚类决策方法在船舶主推进系统的健康状态评估上的应用，重点运用层次分析决策方法对主推进系统的装置进行维修决策的研究，以此算法为基础，建立了主机曲轴维修的多属性决策的模型，确立了相应的评价准则，最后确定了最佳维修方式。
最后，本文开发了船舶主推进系统的故障分析及维修决策的原型系统，通过该系统，可以很容易的得到主推进系统的相关零部件信息，并进行对主要零部件的重要度分析，确定零部件对系统的重要程度；通过FMEA分析模块，可以建立主推进系统零部件的故障信息库，以便对各种可能故障现象的深入分析，进一步提高零部件的可靠度；而系统的维修信息模块，可以保证在零部件使用期限内的监控，对零部件寿命周期预测提供了很好的参考；最后的维修决策模块，则提供给了设备管理人员一定程度的决策支持，达到成本与效益的兼顾。

Abstract
The ship propulsion system is the power source of the whole ship. The security and reliability of the ship is the basic guarantee of ship which can make ship voyage normally, it also relates to safety of property and life safety of crew. So, the demand of the safety and reliability of ship main propulsion is higher and higher. We should detect fault quickly, precisely and efficiently, and finish the maintenance management, but the traditional ways of fault maintenance have not satisfied the requirements of reliability development, so, it is necessary to use advance mathematical method and computer technology associate with experience to research the main propulsion system.
In this paper, base on the research of home and abroad, and development trend of the ship main propulsion system, introduces the basic structure of main propulsion of ship, analyzes the subsystem’s common fault of main propulsion, and grades the fault influence. Associates with common methods of reliability analysis—fault tree analysis, to analyzes the reliability of main propulsion device, and bases on the traditional fault tree analysis, examples the ship gear box, to research the fault tree reliability simulation, programming the calculation of reliability index, at the end, we get the unit importance, mode importance and reliability parameters, using VC++ and MATLAB mixing programming technology, realizes the analog output of reliability curve.
At the research of maintenance decision of main propulsion system, focusing on the various maintenance method, and details the common decision-mode, and introduces the gray clustering decision-making methods using in the health status assessment of the ship’s main propulsion, in the end, chooses AHP as the main decision-mode of main prolusion, establishes the multiple attribute decision-mode and eva luation standard, to analyze the maintenance-decision of crankshaft, Finally, determines the best maintenance method.
Finally, in this paper, I have developed prototype system which is fault analysis and maintenance-decision of ship main propulsion device; we can gain some information of some parts from this prototype system, and analyze the importance of main parts of the device to get the importance degree of parts. In the FMEA module, we can establish fault information database of main propulsion system’s parts, so as to further analysis of the possible fault phenomenon, and enhance the reliability of parts. In the maintenance information module, can assure the monitoring of parts in lifetime; give a reference of life cycle forecasting of new parts. In the maintenance-decision module, provide with some degree of decision support to equipment management, to achieve both the cost and benefit.
