摘 要：在汽车设计初期，为了更精确地计算前端风量，通过全尺寸风洞测试散热器风量，并运用仿真工具完成模型搭建与精度标定。发现散热风扇采用MRF或RBM仿真模型时，误差可控制在5%以内，符合工程应用要求。标定后的散热风扇模型通过在车型上实际应用，总结出一种散热风扇在整车环境下的性能匹配方法。

Abstract: At the beginning of vehicle design,this paper tests the radiator air quantity through a full-scale wind tunnel to calculate the front air quantity more accurately.It user the simulation tool to build and calibrate the accuracy,which finds that the error can be controlled by less than 5%when the radiator fan uses MRF or RBM simulation model,the requirements of engineering application are satisfied.The calibrated radiator fan model is applied to the vehicle,and a method of fan performance matching in the vehicle environment is summarized.
Key words: vehicle front; radiator fan model; full-scale wind tunnel; accuracy calibration
