船舶用AH32钢常温抗拉强度测量结果不确定度评定OA

Uncertainty evaluation of measurement results of tensile strength of AH32 steel for ships at room temperature

中文摘要英文摘要

开展船舶用AH32钢抗拉强度测量结果的不确定度评定,对规范试验过程和合理使用抗拉强度数据具有重要意义,也可为其他船舶用钢抗拉强度不确定度分析提供参考.对船舶用AH32钢的拉伸试验测量结果不确定度进行评定及分析,依据GB/T 228.1-2021相关要求开展拉伸试验及不确定度评价,合理地确定相关不确定度来源,对材料性能做出适当评价具有可操作性.在某些质量可靠性高的不确定度分析中,引入拉伸速率不确定度,识别不确定度分量的影响程度,可以使不确定度评价具有规范性和针对性.

The case analysis of uncertainty evaluation of tensile strength measurement results of AH32 steel for ships was of great significance to the standard test process and the rational use of tensile strength data,and could also provide reference for the uncertainty analysis of tensile strength of other ship steel.The uncertainty of tensile test results of AH32 steel for ship was evaluated and analyzed.The tensile test and uncertainty evaluation were carried out according to the relevant requirements of GB/T 228.1-2021,and the source of relevant uncertainty was reasonably determined.It was operable to make a proper evaluation of material properties.In the uncertainty analysis of some high quality reliability,the introduction of tensile rate uncertainty and the identification of the influence degree of uncertainty components could make the uncertainty evaluation normative and targeted.
