摘要:
基于山区城市地铁线路条件,建立中国帽阵风地铁车辆模型,选取计算参数并确定评价指标.对横风激扰下的车辆受力进行理论推导及计算分析,得出横风激扰下地铁车辆安全运行的曲线半径和最高车速的限定条件.结果表明:过超高时,外侧横风下车辆易倾覆;欠超高时,内侧横风车辆易倾覆;圆曲线半径增大有利于提高安全性,预设条件下圆曲线半径不能小于770 m;车速的增加会使安全性变差,预设条件下车速不得超过48 km·h-1,以保障运行安全.
Abstract:
Based on the metro lines conditions of mountain city, the dynamic model of the hat gust vehicle system was established, in which the calculation parameters were selected and the evaluation indices were determined. The theoretical derivation and calculation analysis of the vehicle under crosswind were finished, and the radius of the curve and the limit condition of the maximum speed of the metro vehicle under crosswind excitation were calculated. The results indicate that the vehicle is easy to overturn under outside crosswind when the situation is in surplus superelevation, but the vehicle is easy to overturn under inside crosswind when the situation is in deficient superelevation. The increase of the radius of circle curve is helpful to improve the safety, and the radius of circular curve cannot be less than 770 m. The increase of speed will make the safety worse, and the vehicle speed shall not exceed 48 km·h-1 to guarantee the running safety.
