随着地铁列车的发展,地铁列车的速度也在不断提高,其空气动力学性能也表现得愈来愈突出,本文以地铁列车为对象,建立了其外流场气动力学模型,并进行了列车车头绕流场计算与分析,结合地铁列车造型美学要求提出了48°前窗倾角流线型地铁列车车头设计方案,达到地铁列车车头设计空气动力学与美学结构设计的统一。
With the development of subway trains, the speed of subway trains is also increasing constantly, and its aerodynamic performance is also more and more prominent. In this paper, the aerodynamic model of outflow field is established for the subway trains, and the train Based on the calculation and analysis of the flow field around the front of the train, a design scheme of the front 48 ° front window and sleek metro train locomotive is put forward according to the aesthetics of the subway train design to achieve the unification of aerodynamics and aesthetic structure design of the subway train head.
