摘　　要：为了研究最高速度为200 km.h-1客货共线铁路的行车安全性及舒适性,从动态角度出发,基于大系统动力学思想,仿真计算了高低速客货列车以不同速度通过全线时的动力学性能各项指标,根据现行铁道机车车辆动力学性能评定规范对其进行评估。仿真结果表明:在设定的平纵断面及运行条件下,所有列车的行车安全性与乘坐舒适性指标均满足要求,并具有较多的富余量,尤其是平稳性指标属优良等级。In order to investigate the running safety and comfortability of train with a maximum speed of 200 km · h^-1 , on the basis of system engineering and dynamics point, the indices of all kinds of trains at different speeds were calculated for mixed railway with passenger and freight traffic. With the railway vehicle and locomotive specification for the evaluation of dynamics performance and accreditation test, train running safety and comfortability were evaluated systematically. The result shows that all dynamics indices belong to safety grade and there are much of overmeasure under operating condition, especially, the ridding indices belong to fine grade. 4 tabs, 7 figs, 7 refs.
