摘    要:为研究裙板安装对高速列车气动阻力及侧风安全稳定性的影响,用计算流体力学(Computational Fluid Dynamics,CFD)方法分析国外某高速列车转向架及其周边裙板结构对整车气动性能的影响.在无侧风且列车行驶速度为350km/h时,模拟分析不安装裙板及在不同位置安装裙板情况下列车的气动性能;在有强侧风情况下,模拟分析列车在50~350km/h之间不同行驶速度工况时的气动性能.结果表明,列车底部安装裙板可有效降低列车气动阻力,在头尾第1对转向架处安装裙板对列车气动阻力的降低最有效;在强侧风下,列车底部安装裙板会造成列车的侧向力和侧翻力矩加大,降低列车行驶安全性.

关 键 词:高速列车  转向架  裙板  气动性能  侧风

Abstract:To study the influence of installation of skirt plates on aerodynamic drag and crosswind safety and stability of high speed train, the influence of bogie and its surrounding skirt plate structures on the aerodynamic performance of a foreign high speed train is analyzed using Computational Fluid Dynamics (CFD) method. Under the crosswind free condition, the aerodynamic performance of the train running at 350 km/h is simulated and analyzed in the cases of no skirt plates installed or installing skirt plates at different locations. Under the strong crosswind condition, the aerodynamic performance of the train running at speed between 50 km/h and 350 km/h is simulated and analyzed. The results indicate that the aerodynamic drag can be decreased obviously when the skirt plates are installed at the bottom of the train, while the aerodynamic drag can be decreased most effectively by installing skirt plates at the places of the first pair of bogies in the train head and the train tail. Under the strong crosswind condition, the lateral force and roll torque of the train are increased by installing skirt plates at the bottom and the driving safety is reduced.
Keywords:high-speed train  bogie  skirt plate  aerodynamic performance  crosswind
