摘要
轴重对轮轨作用力及车辆的动力学性能有显著的影响。分析研究了不同轴重货车的动力学性能,得出了轴重增加使轮轨作用力增加的结论。得出了与30 t轴重货车相匹配的较佳运行速度值,并得到了比较适宜的车轮直径选择数值。
Axle - load has an important effect on the dynamic performance of the wagon. In this paper, the dynamic performance of the wagon with different axle - load was analyzed, and the conclusion that wheel - track interaction forces increase with the increasing of the axle - load was made. At the same time, a research has been done in order to find out the best matching speed and the proper wheel diameter for the wagon with 30t axleload.
