【摘要】：船舶动力系统包括主机、齿轮箱、联轴器、轴系、螺旋桨等设备，是船舶的核心部分。船舶柴油机动力系统集成技术的发展，已成为全球造船业关注的重点，也是世界造船国家竞争的关键。提高我国船舶柴油机动力系统的发展水平，解决动力系统设计的关键技术，实现船舶动力系统产品的本土化成为船舶科技领域的一个重要课题。本文分析并梳理了船舶柴油机动力系统中关键技术的理论知识，在此基础上编写了设计流程，并使用MATLAB软件编程，设计开发了一个集船舶柴油机动力系统设计选型与综合评价为一体的软件系统，其中软件系统的主要设计点是：（1）、机桨匹配设计中采用Kt、Kq回归公式法进行回归计算，避免了使用图谱设计的麻烦；（2）、主机选型部分，低速机采用“机配桨”方法选型，中速机采用模糊评判法选型，将模糊因素实现量的比较，使选型更具客观性和科学性；（3）、柴油机动力系统综合评价部分，对机桨进行航行特性和系柱特性计算，评判船机桨的配合性能，计算船舶的EEDI能效指数，综合评价船舶是否符合国际海事组织规定的排放标准。针对船舶动力系统设计中设备种类繁多，，存储量大等特点，本文运用了Access2003数据库，结合MATLAB，实现了数据的调用、修改、删除、增加更新等功能，实现了大量数据的存储，方便了数据的使用。设计的软件可以实现各个设计模块之间数据的交换和相互调用，根据各部分之间的相互关系，选择最优的设备进行匹配设计，将软件系统编译成可独立执行的DMEP.exe文件，在运行的计算机上只需安装MCRInstaller.exe，就可以脱离MATLAB环境执行程序。通过应用所开发的软件对不同的船型进行计算和分析，表明软件设计结果符合船舶设计要求，适用范围广，不但可以用于新船的设计选型，也可以对旧船进行更换主机计算，具有较高的应用价值。该软件对使用者专业水平要求不高，只需输入相关参数，即可对船舶柴油机动力系统进行集成设计。
[Abstract]:Ship power system, including main engine, gearbox, coupling, shafting, propeller and other equipment, is the core part of the ship. The development of marine diesel engine power system integration technology has become the focus of global shipbuilding industry and the key to the competition of shipbuilding countries in the world. It is an important topic in the field of marine science and technology to improve the development level of marine diesel engine power system, solve the key technology of power system design, and realize the localization of ship power system product. This paper analyzes and combs the theoretical knowledge of the key technology in the marine diesel engine power system, on the basis of which the design flow is compiled, and the MATLAB software is used to program it. A software system is designed and developed, which integrates the design, selection and comprehensive evaluation of marine diesel engine power system. The main design points of the software system are as follows: (1) the Kt,Kq regression formula method is used for regression calculation in the matching design of engine and propeller. Avoid the trouble of using atlas design; (2) in the selection part of the main engine, the low-speed machine adopts the method of "machinery and propeller", and the medium-speed machine adopts the method of fuzzy evaluation, which makes the selection more objective and scientific by comparing the realization of fuzzy factors; (3) in the part of comprehensive evaluation of diesel engine power system, the navigation characteristic and tie-column characteristic of engine and propeller are calculated, the matching performance of ship engine and propeller is evaluated, and the EEDI energy efficiency index of ship is calculated. Comprehensive assessment of whether the ship complies with the discharge standards set by the International Maritime Organization (IMO). In view of the many kinds of equipments and large storage capacity in the design of ship power system, this paper uses the Access2003 database, combined with MATLAB, to realize the function of calling, modifying, deleting, adding update and so on, and realizes the storage of a large amount of data. It facilitates the use of data. The designed software can realize the data exchange and mutual call among the design modules. According to the mutual relations among the parts, the optimal equipment is selected to match the design, and the software system is compiled into a DMEP.exe file which can be executed independently. Simply install MCRInstaller.exe, on a running computer to execute programs out of the MATLAB environment. Through the calculation and analysis of different ship types by using the developed software, it is shown that the software design results meet the requirements of ship design and have a wide range of application. It can not only be used in the design and selection of new ships, but also can be used to calculate the replacement mainframe of old ships. It has high application value. The software does not require a high professional level of the user and can be integrated into the marine diesel engine power system by inputting the relevant parameters.
