铁路超限货车与邻线货车会车距离的计算方法

为解决目前超限货车会车距离的通常计算方法中未考虑超限货物长度,计算点在超限货车纵方向的位置以及超限货车与邻线货车相对停留位置等因素对会车距离计算的影响等问题,采用了超限货车和邻线货车的相对最不利停留位置及其占用的最大空间作为计算会车距离的依据,并分析车辆在直线和曲线上停留工况的基础上,分别推导出直线和曲线上超限货物计算点位于超限货车两转向架中心销之间及外方时会车距离的计算公式,并进行了实例验证. 结果表明,采用该会车距离计算公式,确定的超限货车与邻线货车会车条件更合理、安全.

Calculating Method of Distance Between Railway Out-of-Gauge Goods and Freight Car on Adjacent Track

At present, the distance between out-of-gauge goods and freight car on adjacent track is calculated without considering the influence of length and the calculating point position of out-of-gauge goods. Furthermore, the relative position between out-of-gauge goods and freight car on adjacent track is ignored. This paper puts forward the most unfavorable stop position and the most massive space occupied by the stationary car, which is the foundation of calculation of distance between out-of-gauge goods and freight car on adjacent track. Some formulae of calculating the distance between out-of-gauge goods and freight car on adjacent track, including the formulae whenever the calculating point is located between or beyond the center pins of two bogies of cars on tangent and curved tracks, were deduced and examined. The results indicate that the meeting condition of out-of-gauge goods and freight car on adjacent track according to these formulae will be more reasonable and safer.
