高速铁路车桥仿真计算中列车安全和乘坐舒适度的评定指标

Assessment System of Train Safety and Riding Comfort in Train-Bridge Simulation Calculation of High-speed Railway

介绍了高速列车在过桥时,机车车辆运行安全和舒适评定指标的采样方法,以及安全评定标准,说明了在仿真计算中有关轮重减载率的取值,并对各国高速动力车辆动力学试验安全评估参数限度值进行了汇总。

The paper introduces sampling method of evaluating safety and riding comfort of rolling stock when high-speed train passes a bridge, together with standards of safety evaluation. Value selecting of wheel load reduction rate in simulation calculation is explained, and parameters of safety evaluation of high-speed car dynamics test across the world has been summarized.
