基于Matlab的液体冷却系统仿真与试验验证
|
摘要
冲压空气温度和流量随飞行高度的变化而变化,导致特种飞机上的液体冷却系统存在诸多变化因素,在系统设计初期,计算量庞大且工况复杂。针对上述问题,利用Matlab的Simulink仿真平台,建立液体冷却系统主要部件的动态数学模型和系统仿真模型,并对系统进行仿真分析。将仿真结果与试验数据进行对比,结果表明:仿真分析具有较高的精度,该仿真系统可以用于液体冷却系统的设计和优化。
The temperature and flow rate of ram air changes with the change of the altitude of the aircraft,which leads to many variables for the liquid cooling system of a special aircraft,that means a huge amount of calculation and a set of complicated analysis cases need to be solved in the initial stage of the system design.According to the problem mentioned above,the dynamic mathematical models of main components and the system simulation model of the liquid cooling system are built using Simulink tools of the software of Matlab.The simulation results are compared with the experimental data,which shows that the precision of simulation analysis is acceptable,and the simulation system can be used to design and optimize a liquid cooling system.
