车辆在线路上远行,车轮对轨道产生的作用力,主要是垂直力和水平力。这两个力对线路产生破坏作用,使线路产生不同程度的变形。为了能较客观地评估线路状态的偏差。应根据动力学的原理进行计算,这样得出的结论,与用物理学基础所假定条件评定线路状态及通常工程计算所掌握的情况是相同的。 Vehicles traveling on the line, the wheels of the rail force, mainly vertical and horizontal force. These two forces have a destructive effect on the line, so that the line has different degrees of deformation. In order to more objectively assess the deviation of the line state. The calculations should be based on the principles of dynamics and the conclusions drawn thus far are the same as those obtained by assessing the state of the circuit and the usual engineering calculations based on the conditions assumed by the foundations of physics.
