摘　　要：为了改善工程车辆空气流动状态,利用FLUENT等软件,通过建立风扇风道模型和风扇风室模型,对冷却风扇及其辅助部件在不同组合下的性能进行了仿真分析。最后得到了风扇结构参数和安装位置与其性能的关系,可为工程车辆冷却风扇设计提供一定的参考。In order to improve vehicle＇s state of air flow, fan duct model and fan wind chamber model were set up respectively and used to simulate and analyze the performance of cooling fan and its accessories under different combinations based on FLUENT software. The results show the relationship between structural parameters and arrangement of cooling fan and its performance, which would benefit further design and provide a reference for cooling fan of engineering vehicle.
