| 目前，常用的硬度换算表中均没有表面洛氏硬度HR15YW标尺与其它硬度标尺的换算关系。随着HR15YW硬度标尺的广泛应用，HR15YW标尺与其他硬度标尺的关系研究非常必要。本文通过对不同硬度值的三种材料进行了大量的试验并经过相关性分析得到HR15YW与HR15TW之间存在强正相关关系，利用最小二乘估计原理进行曲线回归分析得到HR15YW与HR15TW的换算关系。对已有换算表进行了补充，从而将HR15YW与其余硬度单位联系起来。 |
| 英文摘要: |
| So far most common conversion tables are not including the conversion relation between Surface Rockwell hardness HR15YW and other hardness. It is urgent to find the relation with the HR15YW and other hardness. This paper will focus on the conversion relation between HR15YW and HR15TW through a large number of experiments on three kinds of materials with different hardness and correlation analysis, curvilinear regression analysis. In this paper, there is a strong positive correlation relationship between HR15YW and HR15TW through a lot of experiments and correlation analysis, and get conversion relation between HR15YW and HR15TW, by using curvilinear regression analysis of the least squares estimate principle. The existing conversion tables are supplemented and the HR15YW could be converted other hardness. |
