摘要
通过对我国机车的牵引能力、机车车辆的制动性能及有关影响因素的研究,提出了确定铁路桥梁最大轨面纵向力的理论计算方法,给出了桥上最大轨面牵引力量值及列车轨面制动力的上限值,并分别用机车额定牵引力和紧急制动状态下桥上最大轨面制动力实测值进行了验证。
Based on the studies of locomotive traction power, braking behavior of vehicles and the factors related, a theoretical calculating method to determine the maximum longitudinal forces acting on rails by train is put forward in this paper. The results calculated, which define the magnitude of the traction force and the braking force limit caused by train, are verified by rated locomotive traction power and urgent braking tests of trains.
