Rolling Friction

Нелинейное Уравнение Ланжевена Для Системы Кулоновских Частиц

“…Уравнение Ланжевена для учета кулоновских столкновений было предложено в работе [17]. Разнообразные подходы для уравнения Ланжевена также обсуждались в работах [18][19][20][21][22].…”

Comments on ‘The abrupt ending of a spinning disk’

“…To be specific, as remarked in [3], the points of the body in contact with the support change over time and then this behavior gives the principal difference between rolling and other types of relative motion (e.g. sliding and spinning).…”

“…The deformations will influence significantly the role the (high) spots play in an abrupt stopping of Euler's disk. We noticed that for investigation of a similar spinning disk's rolling friction, the important role of deformations could be traced in [3][4][5][6][7] with respect to steelʼs deformations (thermal-induced surface damage at contacts possibly due to hightemperature friction in-between) [8,9]. Furthermore, the deformations will possibly change those results as Cross claimed in [1]: possible collisions between the high spots of the disk act to enhance the normal reaction force at those spots, with the result that the offset distance increases as the angle of inclination decreases.…”

“…sliding and spinning). Thus, due to deformations, there is a small contact area and, entering into contact, the body points have a normal velocity proportional to the diameter (of this contact area) [3]. The latter (role of deformation [3]) will influence the changes of the friction coefficient which was not mentioned in [1].…”

The latter (role of deformation [3]) will influence the changes of the friction coefficient which was not mentioned in [1]. Meanwhile it was suggested in [4] that a detailed analysis of energy dissipation via microscopic impacts in a model including (elastic) deformations should be a possible direction of future research.…”
