提高货物列车重量和车辆载重,加快车站编组作业速度,都是提高铁路输送能力的重要措施。这一切都要增加车辆的纵向压缩力,而且迫切需要进一步改进缓冲装置。决定纵向力大小的主要因素是互相冲击的车辆的重量,车辆冲击的相对速度和缓冲器的动力特性。当前,主型车辆——四轴货车——的重量已达93t,而八轴货车的重量为176t。今后,这一重量还会进一步提高。在车辆调车冲击时纵向力和加速度最大,因此缓冲器动力特性的主要指标,通常
Increasing the weight of freight trains and the load of vehicles and speeding up the speed of grouping of stations are all important measures to improve the capacity of railway transportation. All this should increase the longitudinal compression of the vehicle, and there is an urgent need to further improve the cushioning device. The main factors that determine the magnitude of longitudinal force are the weight of the vehicle that impacts on each other, the relative speed of the vehicle impact, and the dynamic characteristics of the bumper. Currently, the main vehicle - a four-axle truck - weighs 93 tons, while an eight-axle truck weighs 176 tons. In the future, this weight will be further enhanced. Longitudinal forces and accelerations are greatest when the vehicle shunts and therefore the main indicator of the dynamic characteristics of the bumper, usually
