材料试验机负荷示值误差的测量不确定度评定

ESTIMATING UNCERTAINTIES OF INDICATED TEST FORCE ERROR FOR MATERIAL TESTER

以WAW-Y500伺服试验机为实例,运用数学模型,对万能材料试验机负荷示值误差的测定不确定度进行分析,为金属拉伸强度指标不确定度的评定提供了依据。

The paper made WAW - Y500 AC Serve tester as instance and used mathematics model to analyze the uncertainties in measurement of indicated test force error of universal tester. In order to offer foundation in the estimating uncertainties of tension strength index of metals.
