基于MATLAB的船舶机舱通风系统仿真
摘要
世界造船业进入了‘数字化’阶段。船舶的每个系统都可以进行建模与仿真。船舶机舱是船舶的动力、电力中心,是轮机人员进行管理的场所。要保证机舱内动力及辅助设备的高效运行,并为工作人员提供舒适的工作环境,必须在机舱内建立并维持适宜的环境条件,船舶机舱通风的目的就在于此。目前在生产单位的设计中,船舶都依据经验来设计机舱通风系统以保证适宜的机舱环境。
本文主要是基于MATLAB平台,针对船舶通风管道网络进行‘数字化’的仿真。为船舶通风设备的制造与运行提供一个理论的支持与数字化的体现,为船舶机舱通风系统的长期运行和舱室内气压的变化提供理论参考。此次仿真是基于集装箱船的通风管道网络设计的,通过风机系统和各个密闭空间模块的差异对船舶通风管道网络进行划分归类,进而对划分的定、变容风机系统模块子系统进行数字建模与界面仿真,同时对每个子系统下的密闭空间模块进行数字建模与界面仿真,最终达到对通风管道网络的界面化,同时可以实时的控制风机的风量以及各个密闭空间气阀的阀值,从而对舱室的气压进行控制与稳定,并且可以动态的显示气压变化趋势的要求。

ABSTRACT
World shipbuilding industry has entered a 'digital' phase. Each ship’s system can be modeling and simulation. Ship engine room is the driving force, power is the engineer who managed the place. To ensure that the cabin power and auxiliary equipment running efficiently and to provide staff with fortable working environment, It must be established and maintained in the cabin suitable environmental conditions. It is the ship engine room ventilation purpose . Currently in the design of production units, based on experience to design vessels are mechanical ventilation system in order to ensure the appropriate cabin environment.
This article is based on matlab platform for ship ventilation works 'digital' in the simulation. Ventilation equipment for the manufacture and ship operation to provide a theoretical support and reflect the number of sub-oriented, for the ship's engine room ventilation system air pressure changes in the long-running and provide a theoretical reference. The simulation is based on the container ship ventilation work design, through the fan system and differences between the various modules confined space ventilation ducts on the ship is works, and thus on the division of fixed, variable volume fan system module subsystem for digital modeling and simulation interface, while the confined space under each subsystem modules for digital modeling and simulation interfa
