Influence of aerodynamic braking on the pressure wave of a crossing high-speed train

Abstract：When aerodynamic braking works,the braking wings can change the flow field around the train,which may impact on the comfort and safety.Based on a sliding mesh,the pressure wave and flow field around high-speed trains with aerodynamic braking are analyzed.By comparing three typical intersection situations,the pressure wave of a high-speed train during braking (with or without aerodynamic braking) is studied.The analyses indicate that the pressure wave around the high-speed train body will change while using the aerodynamic braking,causing several pressure pulses on the surface of crossing high-speed trains.The distances between the pressure pulses are equal to the longitudinal distances of the brake wings,but the magnitudes of the fluctuations are less than those induced by the head of crossing trains.During the crossing,a train without aerodynamic braking will not impact the crossing train. 作者： Author： Meng-ling WU  Yang-yong ZHU  Chun TIAN  Wei-wei FEI 作者单位： Research Institute of Railway & Urban Mass Transit, Tongji University, Shanghai 200092, China 期 刊： 浙江大学学报（英文版）（A辑：应用物理和工程）   ISTICEISCI Journal： Journal of Zhejiang University Science A 年，卷(期)： 2011, 12(12) 分类号： U271.91 Keywords： Aerodynamic braking    High-speed train    Crossing air pressure    机标分类号： N0 V1 机标关键词： pressure wave    flow field    impact    during    typical    works    three    mesh 基金项目： the National Key Technology R&D Program of China
