[Abstract]:According to the general process of mathematical simulation, this paper simulates and studies the liquid cargo handling system of domestic 3600m3LPG ship in Yangzhou Kejin Shipyard. First of all, the working principle of this system and related system is analyzed for the liquid cargo loading and unloading system of domestic 3600m3LPG ship in Yangzhou Kejin Shipyard. Secondly, a mathematical model is established for the main components of the full pressure LPG cargo handling system, such as liquid cargo pump, pipeline valve and cargo tank, and the hydraulic analysis of the liquid and cargo pipeline network is carried out, and the corresponding mathematical model is established. The hydraulic control system, inert gas system, cabin washing system and ship floating state are also modeled. Thirdly, the simulation flow of the equipment, mechanism and monitoring and alarm system in the liquid cargo loading and unloading system is established, and the application software is developed based on the simulation flow. Finally, using the modern simulation software design method, the graphical interface and control program of the simulation software are developed in the Visual Studio2010 integrated development environment, each functional module of the system is constructed and realized, and the automatic simulation of the LPG cargo and liquid loading and unloading system is completed. Finally, the feasibility of the simulation software is verified to ensure that the developed real-time simulation software has accurate data, accurate response and reliable function. The simulation software of liquid cargo loading and unloading can automatically collect the parameters of liquid level, pressure, flow rate and so on. After analyzing and judging, it can transmit the data, display the data in real time and alarm the trouble, and then guide the operation of loading and unloading accurately. The realization of the system is a further attempt to automate and intelligently operate the liquid and cargo system, which can provide a theoretical reference for the further research of the combination of multiple directions. The development of the LPG tanker handling simulation software will further improve the research and development of the marine engine simulator and enrich the spectrum and function of the marine training equipment.
