论中国大型货车的发展方向——轴重提高到23t及25t的可行性

THE DIRECTION OF DEVELOPMENT OF LARGE FREIGHT CARS IN CHINA'S RAILWAYS——THE FEASIBILITY FOR HEIGHTEN THE AXLE LOAD TO 23t AND 25t

作者对发展我国大型货车的两种途径:提高轴重或增加轴数的利弊作了深入探讨,认为应以提高轴重为发展方向。文中着重论述车辆轴重提高到25t及23t后,这些车辆与轨道、桥梁的相互关系等问题。通过试验和数据分析,认为我国当前发展25t及23t轴重货车是可行的。

Two ways for develop large freight car in Chinas railways: heighten axle load or increasing axle numberare deeply discussed in this paper, and is hold that the heighten axle load is the direction Of development. Asthe axle lond heightening to 23t and 25t, emphatically examine the relationship of wheel/rail and after ana-lyzing a large number of testing data, it is hold that freight cars of axle load 23t and 25t is feasible at presentin our country.
