为了研究驱动力或制动力对机车车辆动特性的影响，用一台单车辆模型对机车车辆受驱动扭矩作用时的动特性进行了数值模拟解析，得到了如下结论：（1）当机车车辆上无驱动扭矩作用时，用驱动模型和原有模型进行计算没有区别；（2）当驱动扭矩增大时，蛇行极限速度提高；（3）由驱动扭矩引起的纵向蠕滑力在线性范围内时，因驱动扭矩而造成的影响很小，但如果在非线性范围内，则其影响变大；（4）当纵向蠕滑力呈饱和状态时，轮轴的横向变位很小，并且纵向蠕滑力的变动和横压也很小；（5）当轮／轨间摩擦力很小时，驱动扭矩对机车车辆的动特性会产生一定影响。
In order to study the influence of driving force or braking force on locomotive vehicle dynamic characteristics, a single vehicle model is used to analyze the dynamic characteristics of locomotive vehicle under driving torque. The following conclusions are obtained: (1) There is no difference between the driving model and the original model when there is no driving torque. (2) When the driving torque increases, the mean speed of the snake is increased. (3) When the longitudinal creep force caused by driving torque is within the linear range , The influence caused by the driving torque is small, but the influence is larger if it is in the non-linear range; (4) When the longitudinal creep force is saturated, the lateral displacement of the axle is small and the longitudinal creep (5) When the wheel / rail friction is very small, the driving torque will have a certain influence on the dynamic characteristics of rolling stock.
