控制编组场车辆溜放速度对于车辆的安全连挂和提高编组作业效率是至关重要的。由于常规编组场控制点(缓行器段)很少而且间隔相当大,因此,必须准确地预测这些控制点之间和这些控制点之外的自由溜放车辆的速度。准确预测车辆溜放速度的关键是要掌握有关车辆的走行特性或车辆走行阻力数据,铁路界普遍认识到车辆走行阻力数据的重要性。在现代化编组站测量走行阻力值是例行程序。这些阻力值数据在提供给车辆实时控制的算式和各种
Controlling the speed of yard roll-up in the marshalling yard is crucial for the safe attachment of vehicles and the improvement of the efficiency of marshaling. Due to the few and often large intervals of conventional marshalling yard control points (buoyant sections), the speed of free-slip vehicles between these control points and beyond these control points must be accurately predicted. The key to accurately predict the speed of vehicles is to grasp the driving characteristics of the vehicle or the vehicle running resistance data. The railroad industry generally recognizes the importance of vehicle running resistance data. It is routine to measure travel resistance at a modern marshalling yard. These resistance value data are provided to the vehicle in real-time control of the formulas and various
