摘　　要：基准级渐开线测量仪的基圆盘是形成理论渐开线的基准件,其在导轨上滚动时,由弹性变形引起的轮轨蠕滑是值得探讨的问题。介绍基于有限元法,使用ANSYS工具,分析计算了钢基圆盘在大理石导轨上滚动的弹性蠕滑区间及蠕滑率,数据结果为轮轨不同材料情况下,蠕滑率对测量仪不确定度评定的影响提供了重要的参考依据。The basic disc on the double-disc measuring apparatus of involute tooth profile is a base part to form theory involute,when it roll on the rail,the wheel-rail creep caused by elastic deformation is worthy of examination. The rollingflexibility creep phenomenon of disk on the marble-rail has been analyzed based on the finite element method,using ANSYS soft. The result are useful information for the impact of the wheel-track different materials creep on the tooth profile measuring instrument accuracy deviation.
