摘　　要：回弹仪的弹击拉簧刚度是回弹仪检定项目中十分重要的技术指标。本文根据JJF1059.1-2012《测量不确定度评定与表示》和JJG 817-2011《回弹仪检定规程》,对回弹仪的两种不同拉簧刚度的检定方法进行研究,并对其测得值及不确定来源进行分析与评定,为实际检定/校准回弹仪提供了参考。Spring stiffness of spring rebound instrument is a very important technical index in the verification of spring rebound instrument.According to JJF 1059.1-2012"Evaluation and Expression of Uncertainty of Measure-ment"and JJG 817-2011"Verifcation Regulation of Springback Instrument",this paper studies two different ver-ifcation methods of spring stiffness of springback instrument,analyzes and evaluates the measured values and sources of uncertainty,and provides a reference for the actual verification/calibration of springback instrument.
