摘要
在MATLAB/SIMULINK环境下建立了机载蒸发循环制冷系统的仿真模型。分别在3种典型工况下对系统进行了仿真计算并在相同工况下在蒸发循环制冷系统试验平台上进行了地面试验,得出了影响系统性能的主要参数和影响程度,以及不同工作状态下各参数的变化规律。通过比较仿真与试验结果,证明仿真结果基本正确,采用蒸发循环制冷系统的仿真方法可行。仿真结果可为机载蒸发循环制冷系统的理论研究和设计提供参考。
The simulation model of airborne vapor cycle system is established using MATLAB/SIMU- LINK technique. Simulation calculation of the system is carried out respectively in three typical operating conditions, and ground tests in the test platform are carried out in the same conditions, then the research finds the main parameters that affect the system performance and their effect degree, and gets the change law of these parameters under different working conditions. The comparison of simulation results and experimental results prove that the simulation results are basically correct, and simulation method of the vapor cycle system is feasible. The simulation results can be a basis of the theory research and design of airborne vapor cycle system.
