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.

Analysing the methods for determining coefficient of resistance to car wheels rolling [PDF]
Avtomobilʹnyj Transport (Harʹkov), 2020 Problem. When simulating the operation of automatic or automated driver assistance systems, it is necessary to take into account the rolling resistance of the car wheels the moment the car begins to move on a slope, which necessitates the choice of a ...

PASSIVE TORQUE SIMULATION OF SMALL ANGULAR CONTACT BEARING AT HIGH SPEED [PDF]
, 2017 Description of common ball bearing torque models was presented and adopted to the complex thermo-mechanical model of the high speed spindle. Ball bearing passive torque was measured on the own high-speed spindle design.

Wheelchair tire rolling resistance and fatigue
The Journal of Rehabilitation Research and Development, 1985 The hysteresis loss theory of rolling resistance is developed for solid rubber wheelchair tires. The analysis is used to correlate test data for a clay-filled natural rubber and a polyurethane tire material. A discussion of tire rolling work, hysteresis loss factor measurement, and rolling loss measurement is presented.

Cohesive, frictional powders: contact models for tension [PDF]
, 2008 The contacts between cohesive, frictional particles with sizes in the range 0.1–10 μm are the subject of this study. Discrete element model (DEM) simulations rely on realistic contact force models—however, too much details make both implementation and ...

Analytical method for establishing indentation rolling resistance
E3S Web of Conferences, 2018 Belt conveyors are highly reliable machines able to work in special operating conditions. Harsh environment, long distance of transporting and great mass of transported martials are cause of high energy usage.

Identification of rolling resistance as a shape parameter in sheared granular media
, 2011 Using contact dynamics simulations, we compare the effect of rolling resistance at the contacts in granular systems composed of disks with the effect of angularity in granular systems composed of regular polygonal particles.

On Rolling Resistance of Bicycle Tyres
, 2022 This paper describes a method that enables comparative rolling resistance measurements of bicycle tyres on different road surfaces. The test equipment is a one degree of freedom two-wheeled pendulum with a rigidly coupled eccentric weight. Derived from the conversion of potential energy into dissipated heat by means of rolling resistance losses the ...
