摘　　要：运用多重参考坐标系(Multiple Reference Frame)方法对工程机械用发动机冷却风扇的内部流场进行数值模拟,获得了风扇内部流场数据,如压力场、速度场,详细分析了风扇的内部流场特性,并探讨了不同发动机转速对风扇流量特性的影响。通过与试验结果对比,表明用多重参考坐标系方法模拟风扇内部流场的正确性和可靠性,为优化发动机冷却风扇性能提供参考依据。We utilized a multiple reference frame to make numerical simulation of internal flow field characteristics of engine cooling fan for construction machinery and have got the relevant data, such as pressure field, velocity field etc. We have made detailed analysis of the internal flow field characteristics of engine cooling fan, while investigating how the engine's various RPM affects its flow features. Comparison of test results shows that it is correct and reliable to use the multiple reference frame as a way to simulate the internal flow field of the cooling fan, thus providing basic reference for optimizing the function of engine cooling fan.
