【摘要】：随着燃油价格的不断上涨以及节能减排的日益严格，渔场的经营成本也不断上升。这时开展基于导管桨和双速比齿轮箱的拖网渔船机桨匹配软件开发的研究，利用现代计算机技术方便、快捷的研究拖网渔船的主推进系统，促使拖网渔船高效、经济、绿色环保的营运也成为了国内外学者研究的焦点。本文在系统分析了拖网渔船阻力特性、拖网渔船主机特性及选型、双速比减速齿轮箱推进特性及选型、导管桨推进特性的基础上，梳理了拖网渔船机桨匹配图谱设计方法的计算流程，编写了拖网渔船机桨匹配设计思想总流程程序方框图以及其各子系统的程序方框图，并运用MATLAB程序语言将其开发成了一个软件。然后借用42m级拖网渔船对新开发的软件进行了应用研究，，应用结果表明：本软件的设计结果和实船误差很小，设计结果也完全符合拖网渔船的初始设计要求。本文研究结果表明：新开发的基于导管桨和双速比减速齿轮箱拖网渔船机桨匹配设计软件开发计算精度高，使用方便快捷，对使用者的专业水平要求不高，具有一定的工程应用价值。
[Abstract]:With the rising of fuel price and the increasingly strict energy saving and emission reduction, the operating cost of fishing ground is also rising. At this time, the research on the development of the matching software of trawler engine and propeller based on ducted propeller and double speed ratio gearbox is carried out. It is convenient and quick to study the main propulsion system of trawlers by using modern computer technology, which promotes the efficient, economical and green operation of trawlers, which has also become the focus of scholars at home and abroad. In this paper, the drag characteristics of trawlers, the characteristics and selection of main engine of trawlers, the propulsion characteristics and selection of gear box with double speed ratio, and the propelling characteristics of ducted propellers are analyzed systematically. Combing the calculation flow of the design method of the matching map of the trawler engine and propeller, the program block diagram of the total flow chart of the design idea of the trawler engine and propeller matching and the program block diagram of its subsystems are compiled. And use MATLAB program language to develop it into a software. Then the application of the newly developed software is studied by using 42m trawler. The application results show that the design result of the software and the actual ship error are very small. The design results also fully meet the initial design requirements of trawlers. The research results show that the newly developed design software for propeller matching of trawler trawlers based on ducted propeller and double speed ratio gearbox is of high precision, convenient and quick to use, and the professional level of users is not high. It has certain engineering application value.
