| 摘 要： | 动车组头型不同,对气动力学效应的影响也不尽相同。为探讨头型对动车组隧道气动效应的影响,将CRH2C型动车组和在其基础上进行头型优化改进的CRH380A型动车组在不同工况下的试验数据进行对比分析,结果表明头型的改进有利于改善动车组的车外流场分布,有利于提高旅客乘坐舒适度。

| Abstract: | EMUs have different aerodynamic effects due to different nose shapes. In order to investigate their aerodynamic effects in tunnels, the test data of CRH2c EMU have been compared under different running conditions with those of CRH380A EMU, which is an improved version based on the former. The results show that the improvement of nose shape will help to improve the distribution of external pressure field and passenger comforts. |
