在本研究中，研究了扁钢表面与钢辊接触处的起始滚动位移的详细行为。此外，通过改变滚动接触表面的硬度和滚子的半径，对起始滚动距离区域中形成的磁滞回线的行为进行了实验检验。结果发现，接触宽度与滚动摩擦力密切相关，磁滞回线的面积与起始滚动距离的二次方成正比，磁滞回线的最大宽度与赫兹理论计算的半接触宽度几乎相同。
In this study the detailed behaviour of the starting rolling displacement at the contact of a flat steel surface with a steel roller is investigated. In addition, the behaviour of the hysteresis loop formed in the region of the starting rolling distance is experimentally examined by varying the hardness of the rolling contact surface and the radius of the roller. From the results it is found that the contact width is closely related to the rolling friction force, that the area of the hysteresis loop increases proportionally to the second power of the starting rolling distance and that the maximum width of the hysteresis loop shows almost the same value as the half-contact width calculated by Hertz' theory.
