摘　　要：通过分析牵引质量的计算原理,对公铁两用牵引车的运行牵引阻力和牵引车辆的运行牵引阻力分别进行了推导计算,得到了牵引作业时的总运行阻力;同时,对现有列车牵引特性曲线及牵引计算数据进行了类比分析,得出了公铁两用牵引车的持续速度和持续牵引力两个关键指标,最终计算得到了公铁两用牵引车在限制坡道下的牵引质量。In this paper,by analyzing the calculation principle of traction mass,the running traction resistance of the dual-purpose rail-road tractor and the running traction resistance of the traction vehicle are deduced and calculated respectively,and the total running resistance during the traction operation is obtained.Meanwhile,the existing train traction characteristic curves and traction calculation data are analogously analyzed,and the two key indicators of the continuous speed and continuous traction force of the dual-purpose rail-road tractor are obtained.Eventually,the traction mass of the dual-purpose rail-road tractor on the limiting ramp is calculated.
