| 摘 要： | 对空调导流罩的原始结构进行了外流场分析,得到了在350 km时速下原空调导流罩的外表面压力分布和速度场分布,通过对速度的流向分析,对空调导流罩的外形结构进行了优化。利用风洞试验对优化前后2种方案进行了气动阻力系数对比,结果表明,优化后的空调导流罩使头车的气动阻力减小了2.6%,改善了车辆的空气动力学性能,并为高速列车空调导流罩的基本造型设计提供了理论依据。 |

| Abstract: | The external flow field analysis is made on the original structure of the air-conditioning domes.The external surface pressure distribution and speed field distribution of the original air-conditioning domes at the speed of 350 km/h are obtained.Through analysis of the flow direction of speed,the external structure of air-conditioning domes is optimized.The aerodynamic resistance coefficients of the two schemes before and after optimization are compared with the use of air tunnel test,and the result shows t... |
