Rolling friction for hard cylinder and sphere on viscoelastic solid
, 2010 We calculate the friction force acting on a hard cylinder or spherical ball rolling on a flat surface of a viscoelastic solid. The rolling friction coefficient depends non-linearly on the normal load and the rolling velocity.

Study on Wear Characteristic of Rolling Bearing Caused by Rolling-sliding Motion
Jixie chuandong, 2021 Rolling-sliding motion is a special motion form which leads to the failure of rolling bearings. In order to study the wear characteristics of rolling bearings under rolling-sliding motion， the method of combining simulation with experiment is adopted ...

Determination Method of Coefficients of Particle and Rolling Friction in Distinct Element Method
Journal of the Society of Powder Technology Japan, 2019 A new method to determine both the coefficients of particle and rolling friction in distinct element method (DEM) was proposed. The coefficients are two of the most important parameters which have great effect on particle behavior in DEM.

Jamming transition in a two-dimensional open granular pile with rolling resistance
, 2014 We present a molecular dynamics study of the jamming/unjamming transition in two-dimensional granular piles with open boundaries. The grains are modeled by viscoelastic forces, Coulomb friction and resistance to rolling.
