High-speed 3D digital image correlation for measuring tire rolling resistance coefficient
Measurement, 2021Abstract A novel method is proposed to measure rolling resistance coefficient of high-speed running tire. Compared with the existing rolling resistance coefficient measurement methods, the new approach is non-contact measurement based on the calculation of relative flexible principal strain rate.

The coefficient of rolling resistance (CoRR) of some pharmaceutical tablets
International Journal of Pharmaceutics, 2010Experiments have been conducted to measure the coefficient of rolling resistance (CoRR) of some pharmaceutical tablets and several common materials, such as glass beads and steel ball bearings. CoRR values are required as inputs for discrete element method (DEM) models which can be used to model particulate flows and solid dosage form manufacturing ...

Method of estimating the rolling resistance coefficient of vehicle tyre using the roller dynamometer
Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2020The tendency in the past few years has been to introduce tyres with lower rolling resistance coefficients to the market. This paper presents a mathematical method for determining the rolling resistance coefficients variation depending on the speed.

The coefficient of rolling resistance (C r) for pneumatic tyres is dependent on hysteresis loss from tyre deformation which is affected by the vertical force applied to the tyres (F v) and the tyre inflation pressure (P r). The purpose of this paper was to determine the relative influence of five different levels of P r and four different levels of F v

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.
