摘要
对速度在100km/h到400km/h区间,装有风阻制动板的高速列车进行了数值仿真计算。在面积相同的情况下,研究了不同形状的风阻制动板所产生的制动力值,并对空气动力制动产生的制动动力效果进行了分析。仿真结果表明,带有风阻制动板的列车在整车气动阻力上远大于原型车,且随速度的提高而制动阻力效果更加明显;在相同面积下,不同摆放形式的风阻制动板会产生不同的制动效果,综合比较下,2块分开放置的风阻制动板是最优方案。
The numerical simulation calculation is made for the high-speed train mounted with the air resistance brake panel, from 100 km/h to 400 km/h. The value of the braking force generated by the different air resistance brake panel is obtained in the same area, an analysis is made of the braking force effect generated by aerodynamic brake. The results show that, the resistance is much greater than the prototype vehicle with drag brake panel train in the aerodynamics of vehicles, and the braking effect is more obvious with the speed increasing. In the same area, the different drag brake panel form will produce different braking effects. A comprehensive comparison shows that the two separate drag brake panel is the optimal scheme.
