国外高速列车最佳头尾部形状的研究

Research on optimum nose and tail shapes of foreign high-speed trains

针对国外利用以风洞模型模拟试验和以流场数值模拟计算为主的方法来寻求高速列车最佳的头尾部形状 ,使列车的综合气动性能最佳 ,从而有效地降低空气动力学现象对列车运行和周围环境的影响进行了探讨 。

Based on methods of foreign countries of using wind tunnel test and numerical flow simulation,optimum nose and tail shapes of high speed trains are studied to achieve optimum aerodynamic performance so as to efficiently reduce the influence of the aerodynamic phenomena on the train operation and the environment.Research results of foreign countries are introduced.
