力学测试中的不确定度评定

The Evaluation of the Uncertainty in the Mechanical Property Testing

简要介绍了测量不确定度的基本概念,同时对力学测试中测量不确定度的评定过程和基本方法进行了论述。评定了力学测试中钢材拉伸试验的相对不确定度,验证了实验室日常检测结果的可靠程度。

The basic concept for the uncertainty of the testing has been described in this article, as well as the evaluation process and the basic method of the uncertainty during the mechanical property testing. And the relative uncertainty of the steel tensile testing during the mechanical property testing has been well evaluated, so that reliability of the conventional testing results in the laboratory has been verified as well.
