【摘要】 基于SIMPACK动力学软件创建了适用于160 km/h市域快速轨道交通的车线动力学仿真模型,在不同竖曲线半径的纵断面线路上进行了仿真分析。结果表明:车体垂向加速度最大值随着竖曲线半径的增大而减小,两者成二次降函数关系;建议160 km/h市域快速轨道交通的车体垂向加速度允许值取0.17 m/s2,最小竖曲线半径取12 km。更多还原

【Abstract】 A vehicle-rail dynamic simulation model for 160 km/h urban rapid rail transit was established based on SIMPACK dynamics software,and the simulation analysis was carried out on the vertical section railway lines with different vertical curve radius.The results show that the maximum vertical acceleration of train decreases with the increase of the vertical curve radius and the relationship between them is quadratic descending function.It is suggested that the train allowable vertical acceleration of 160 km/h urban rapid rail transit should be 0.17 m/s2 and the minimum vertical curve radius should be 12 km.更多还原
