摘　　要：本文针对动车轮轴、毂及联轴节表面划痕的特征,进行了测量工艺的研究,提出了可视化接触式测量的工艺方案;研发了一款新型适于动车轮对及联轴节轴孔划痕测量仪。介绍了测量仪的工作原理与基本组成;并对其精度与可靠性进行了理论分析与实验研究。Based on the surface scratch characteristics of the wheel shaft, hub and coupling, this paper carries on the research of the measurement process and puts forward a process scheme of the visual contact measurement. A new type scratch measuring instrument suitable for the wheel and the coupling of the bullet trains is designed. This paper introduces the operating principle and basic composition of the instrument and carries on the theoretical analysis and experimental research for the accuracy and reliability of the instrument.
