摘要:本文建立了汽车发动机冷却系统的动态特性仿真模型,并在MATLAB/SIMULINK中对模型进行仿真计算。主要对汽车在启动、加速、减速三种情况下冷却系统的传热特性进行仿真,并将仿真结果与实验数据进行比较分析,仿真结果与实验值的相对误差在±3%以内,表明笔者的建模方法是合理的。

Abstract: A mathematical model describing
the dynamic performance of vehicle engine cooling system is established and
computed in MATLAB/SIMULINK in this paper.It is related to three cases inclding
starting,accelerating,decelerating.All obtained results are compared with
experimental data,which shows that the relative error can be correlated
within.It is confirmed that the method of mathematical model is correctly.
Keywords: Vehicle Cooling System;Dynamic
