摘　　要：应用AMESim软件建立了某排量为1.5L的发动机冷却系统的一维仿真模型,利用该模型进行发动机冷却系统各工况点冷却性能的计算,分析了该冷却系统在不同工况下的冷却能力。研究发现,在高温长时间爬坡的工况下,发动机冷却系统的冷却能力难以满足散热要求,易引起发动机出现"开锅"现象。通过对冷却系统的零部件参数进行重新匹配,提出了对原有冷却系统中节温器、风扇的相关参数进行重新匹配的解决方案,并验证了该方案的有效性,研究结果为整车厂和配套厂对冷却系统零部件的选型和开发提供了参考。A 1D simulation model of 1.5L engine cooling system was established using AMESim, cooling performance of various condition of engine cooling system were calculated, and the cooling capacity of cooling system under different condition points has been analyzed. The study find that under high-temperatures long-time climbing conditions, the cooling demand of the engine cooling system is diffwult to be met, which can lead to a ＂boil＂ phenomenon. By re-matching the parameters of parts of the cooling system, solutions of re-matching the parameters of thermostat and fan of the original cooling system were proposed and the effectiveness of the scheme were verified. The results of the study provide the reference of the selection and development of cooling system parts for vehicle and ancillary plant.
