Abstract

This study is devoted to the development of a mathematical model of the rolling friction process of elastic bodies. It is shown that rolling friction has a dual character, since it depends on the microslip forces of the contacting surfaces and on the adhesion forces on the contact surface. The influence of adhesion forces on rolling resistance prevails in cases where the line of contact of bodies is close to a straight line, for example, when a roller rolls on a plane or when two identical balls roll, and the forces caused by microslippage of surfaces prevail with a curved line of contact, for example, when a ball rolls on a narrow groove. The results of modeling are compared with the results of experimental studies previously carried out by Pinegin, who confirmed the adequacy of the mathematical model.

弹性体滚动阻力过程的建模
本研究致力于建立弹性体滚动摩擦过程的数学模型。结果表明,滚动摩擦具有双重特性,既取决于接触面的微滑移力,又取决于接触面上的粘附力。在物体接触线接近直线的情况下,例如,当滚子在平面上滚动或两个相同的球滚动时,附着力对滚动阻力的影响普遍存在,而表面微滑移引起的力在弯曲的接触线中占主导地位,例如,当球在狭窄的凹槽上滚动时。将建模结果与Pinegin先前进行的实验研究结果进行了比较,证实了数学模型的充分性。
