Simulation Design of Heat Balance of Central Cooling System of a Dredger Based on Matlab Simulink

以某耙吸式挖泥船的中央冷却系统热平衡计算为研究对象,建立Simulink仿真模型,进行仿真计算及结果验证。实践证明,利用数学软件Matlab Simulink分析软件,通过建立数学模型,并利用Simulink特点进行模块化建模,将系统图转化成数学模块流程图,并进行合理的参数定义,对船舶中央冷却系统进行动态仿真,可提高工作效率和可视性,实现动态监控。

Taking the heat balance calculation of the central cooling system of a trailing suction dredger as an example,a Simulink simulation model is established for simulation calculation and result verification.Practice has proved that using the mathematical software MATLAB Simulink analysis software,through the establishment of mathematical models,and using Simulink features for modular modeling,the system diagram into mathematical module flow chart,and reasonable parameter definitions are made to dynamically dynamic the ship’s central cooling system,which improve the work efficiency and visibility,realize the dynamic monitoring.
