有关机车车辆的横向性能问题,在设计时要进行综合考虑。特别是走行性能必须同车轮磨耗所需要的维修相权衡。这些方面的问题,目前还没有一个统一的最佳解决方案。本文介绍了所预计的有效方法及其研究要点。并以两种车辆的设计方案为例作了说明,但距离得到最佳方案还需要做大量的工作。 The horizontal performance of rolling stock on the issue of design to be considered. In particular, running performance must be balanced with the maintenance required for wheel wear. At present, there is not a unified best solution to these problems. This article describes the expected effective methods and their research points. The design of the two kinds of vehicles is taken as an example to illustrate this, but a lot of work needs to be done to get the best solution from the distance.
