我们研究了由两台八轴电力机车和200辆轴载荷为250kN的四轴货车所组成的20000t列车的制动过程。一台机车位于列车头部,另一台机车位置有两个方案:一个是位于列车中央;另一个是位于距列车尾部三分之一的列车长度处。作为比较,还研究了两台机车都放于列车头部的情况。车辆都装用No.483型排风孔直径为0.9mm的空气分配阀,带有Ⅲ-1TM型缓冲器的自动车钩和合成闸瓦。车辆间连接器的间隙取为45mm,符合新造车的要求。
We studied the braking process for a 20000t train consisting of two eight-axis electric locomotives and 200 four-axle trucks with 250kN axle loads. One locomotive is located at the head of the train and the other locomotive has two options: one at the center of the train and the other at a train length one-third the distance from the rear of the train. As a comparison, we also studied the situation where two locomotives were placed on the train’s head. Vehicles are equipped with No.483 air distribution valve diameter of 0.9mm vent, automatic coupler with Ⅲ-1TM buffer and synthetic brake shoe. Inter-vehicle connector gap taken as 45mm, in line with the requirements of the new car.
