在有许多小半径曲线的线路上,客车运行的时间在原则上可用两种方法予以缩短:取直线路和制造在现有曲线能高速运行的车辆。取直线路牵涉到很大的工作量,往往在经济上是很不合理的。许多线路由于地理条件,取直线路常常是不可能的。所以制造在现有线路上高速运行的车辆是最适宜的。这时最重要的任务是保证旅客有足够的舒适度。确定列车在曲线上允许运行速度的标准之一是转向架簧下部分未被平衡的水平横向加速度a_H。苏联铁路将该参数的极限值根据
On lines with many small radius curves, bus operation can be shortened in principle in two ways: by taking straight lines and by making vehicles that can run at high speeds on existing curves. Taking a straight line involves a lot of workload, often in the economy is very unreasonable. Many lines are often impossible to get straight because of the geographical conditions. Therefore, it is most suitable to manufacture a vehicle running at high speed on existing lines. At this time the most important task is to ensure that passengers have enough comfort. One of the criteria for determining the speed at which the train is allowed to travel on the curve is the unbalanced horizontal lateral acceleration a_H of the unsprung part of the bogie. Soviet railway will be based on the limits of this parameter
