论述了在机车车辆的研制阶段所进行的开发过程以及灵活使用缩小尺寸的物理模型进行定置试验对掌握机车车辆的走行稳定性、走行安全性和乘坐舒适性的重要性。同时介绍了与试验相关的轮轨试验台、定置试验台的特点及结构；介绍了模型试验本身的优点及对试验结果的评价方法，最后强调了铁路系统进行现场运行试验的重要性。
Discusses the development process of locomotive and rolling stock during the development process and the flexibility to use the reduced size of the physical model for the fixed test to grasp the rolling stock stability of the running, walking safety and ride comfort importance. At the same time, the wheel-rail test bench related to the test is introduced, the characteristics and structure of the test bench are set, the advantages of the model test itself and the evaluation method of the test result are introduced, and the importance of running the test on the railway system is emphasized.
