本文用分析法研究了接触摩擦对较大的压入角的布氏硬度值的影响,得知已建立的标准中d/D的比例范围从0.2～0.6可以扩大到0.7～0.75而并不增加由于接触擦所造成的误差。
In this paper, the influence of contact friction on the Brinell hardness at a large angle of penetration is studied. It is found that the established d / D ratio can be expanded from 0.2 to 0.6 to 0.7 to 0.75 without any increase due to Errors caused by contact rub.
