摘要
本文以大连海事大学陆上机舱建立为契机,通过系统地介绍以及说明中央冷却水系统部件以及设计流程,同时希望通过对设计软件的二次开发来简化设计循环,以达到对中央冷却水系统进行较为系统研究的目的。
在论文开展的实际过程中,主要是通过对设计流程的方法查询,以及通过比对船舶中央冷却水设计的方法来对开展陆上机舱冷却水设计工作。陆上机舱作为可以模拟船舶所有实际功能并应用于教学领域的模拟器来说,它有和船舶很多的相似之处,但从微观角度来看,陆上机舱的特殊性也必须注意到。本文中着重系统设备的角度,将陆上机舱特有的水塔、水力测功器添加到设计流程中,考虑整个系统的冷却量,并加以选型。在具体设计上,通过设计软件AutoCAD的二次开发技术,对后期热平衡图、系统图的绘制工序进行简化。
本文主要通过对大连海事大学陆上机舱中央冷却水系统的设计开展系统设计的研究,对陆上机舱冷却水系统设计提出设计约束以及思路。在陆上机舱中央冷却水系统设计中,通过总体冷却量计算、设备计算、设备选型以及平衡图、系统图的绘制为主要流程进行设计。后期则通过AutoCAD VBA开发,将系统设计通过宏的模式简化于设计软件中。
在通过设计流程的研究,更进一步发现在陆上机舱设计中不可避免的震动问题。而在航海类教育的进一步开展来看,陆上机舱的建立是一个必然趋势,而通过本文的工作,则给陆上机舱系统设计建立中提出一些较为全面的设计方法,同时对陆上机舱的特殊性的阐述也希望可以对陆上机舱设计提出有意义的观点。
In this paper, as an opportunity of the establishment of Dalian Maritime University onshore engine room, through the systematic introduction and explain the central cooling water system components and design process, also hope that by the secondary development of software to simplify the design cycle, in order to achieve the central cooling water system more systematic research.
The actual process carried out in the paper, mainly through the method of inquiry on the design process, especially through compare with the central cooling water of the ship design, to carry out the water cooling system of land-based engine room design. Land-based engine room as the simulator can simulate ship actual function and applied in the teaching fields, it has many similarities to the ship, but from microscopic point of view, the particularity of the land-based must also be noticed. This article focuses on the perspective of system equipment, added the water tower and hydraulic dynamometer to the design process, consider the system of cooling capacity, and make selection. In the actual design, through the use of the AutoCAD design software by secondary development, thermal equilibrium diagram, the system diagram design process can be simplified.
In this paper, through the central cooling water system of Dalian Maritime University land-based engine room design to carry out the system research design. In the central cooling water system of land-based engine room design, switch series of the calculation of the overall cooling, equipment selection and thermal equilibrium diagram, the system diagram design as the main process of the design. After this, through VBA technology to start the secondary development of the AutoCAD, simplified the design process.
Through the research of design process and further found that the land-based engine room design inevitable vibration problem. Maritime education in further perspective, the establishment of land-based engine room is an inevitable trend, and through this paper, the engine room design is to rise up some of the more comprehensive establishment of the proposed design method, while, also hope the specificity mentioned in paper can make meaningful in the design of land-based engine room.
