摘要
提出了利用滚动台测试车辆和动车组机械阻力的方法和原理,对比动车组在实际线路上的实测基本阻力公式,可得到空气阻力及其公式,为分析基本阻力中机械阻力和空气阻力的大小和占比提供了一种途径。
The method ＆ principle for testing mechanical resistance of EMU by using Rolling rig was proposed in this paper. Compared with the resistance formula of EMU on real railway line, the air resistance and its formula can be achieved, which supplies one approach to analysis the size and proportion of mechanical resistance and air resistance in primary resistance.
