CALCULATION OF THE COEFFICIENT OF FREE ROLLING RESISTANCE FOR THE WHEEL WITH DEFORMABLE RIM
Transport engineering, 2022A new method for calculating rolling resistance is developed. This method includes a simplified structural model of a wheel in the form of a rigid cylinder with a thin viscoelastic rim. The wheel loading mode is considered in the absence of shearing (horizontal) force.

Identification of Rolling Resistance Coefficients for Aircraft Tires on Unsurfaced Airfields
Journal of Aircraft, 2007The paper describes four test methods for determining the rolling resistance of aircraft tires on unsurfaced airfields. Evaluations of a flight-test method, an instrumented-vehicle method, a soil stress-deformation method, and a tow-test method were performed on a grassy airfield.

A Method to Determine the Rolling Resistance Coefficient by Means of Uniaxial Testing Machines
Experimental Techniques, 2013The characterization of the rolling resistance is an important issue when designing mechanical systems in order to predict the force needed to run a given mechanism. Frictional forces in bearings and rolling resistance in rollers and wheels are the most important factors contributing to the overall resistance to the movement. As the rolling coefficient
