| 摘 要： | 根据线路－列车动力学的基本原理，利用列车纵向运动仿真系统ＬＱＤ，在大量的计算机仿真实验的基础上，总结出了铁路线路纵断面参数（包括线路坡度、坡段长度、坡度代数差、竖曲线半径）对列车纵向车钩力的影响规律，发现了临界坡度代数差在车钩力与纵断面参数关系中的核心地位，并从列车受力角度提出了纵断面参数的合理取值范围。

| Abstract: | This paper summarized the experiment results which were made by the train movement simulating system LQD programmed on the basic principle of track-train dynamics.The paper found and analysed the relationships between train coupling force and railway profile pararneters which include grade,gradient length,difference in adjacent gradients,and the radius of vertical curve.The key position of critical difference in adjacent gradients in the relationships was found.The paper also put forward the proposed design standards or reasonable values of the parameters for profile designing. |
