船舶推进系统数据库及软件开发

The development of database and software for ship propulsion system

目前,国内的船舶推进系统主要依靠设计人员通过理论计算和必要的经验来完成主要设备参数的确定及选型等,存在设计效率低、难以得到最优方案等问题。针对上述现状,本文在建立船舶低速机推进系统资料数据库的基础上,开发了船舶推进系统计算机辅助设计平台,并对系统平台的关键技术——数据库结构的设计、螺旋桨设计功能的实现及主机和轴系设备选型功能的实现进行了详细的论述。最后,通过26 000吨级成品油船推进系统的设计实例验证了本平台的可行性与方便性,研究成果对推进我国船舶推进系统计算机辅助设计软件的开发具有重要的指导作用。

Marine propulsion system is the source of ship power.Its performance directly affects the operation of the ship.At present,internal ship propulsion system is mainly depended on designers through the theoretical calculations and by the necessary experience to complete the identification of the main parameters and the selection of equipments.But it is difficult to obtain the optimal solutions and design efficiency is low are becoming increasingly prominent.For the status quo,this paper developed the computer-aided de-sign platform of ship propulsion system based on the low-speed marine propulsion system information database and discussed the key technology about the platform in details which include the design of database,the function of designing propeller and the main engine selection function.At last,this paper verified the feasibility and convenience of this platform through the propulsion system design of 26 000DWT tanker.This research has an important role in guiding the development of the computer-aided design software of ship propulsion system in our country.
