列车编成辆数对高速列车横风气动特性影响的数值分析OA北大核心CSCDCSTPCD
Numerical Analysis on the Influence of Train Formation on the AerodynamicCharacteristics of High-Speed Trains under Crosswind
对3～8辆编组列车以350km· h-1速度运行时,不同速度横风作用下的气动特性进行仿真研究,并建立列车的阻力系数与列车编组辆数之间的无量纲关系.研究结果表明:对3辆车编组列车的气动特性分析不能取代对其他编成辆数列车的几动特性分析；不同编成辆数列车阻力系数随着横风风速的增加而增大,3辆车编组列车的阻力系数不超过8辆车编组的列车的一半；列车的侧向力系数和倾覆力矩系数随着列车编成辆数的增加而减小；列车编成辆数对头车的阻力系数、升力系数、侧向力系数和倾…查看全部>>
Simulation was carried out on the aerodynamic characteristics of train consisting of 3~8 cars running at the speed of 350 km · h-1 in crosswind with different velocity. Dimensionless relationship was established between the drag coefficient of train and the number of train formation. Results show that the analysis on the aerodynamic characteristics of train that consists of 3 cars can't replace that of train consisting of other number of cars. The drag coeff…查看全部>>
