Rolling Resistance Revisited

Tire Science And Technology, 2019
ABSTRACT Rolling resistance defined as energy loss per unit distance is well accepted by the tire science community. It is commonly believed that the dominant part of energy loss into heat is caused by the viscoelasticity of rubber compounds for a free-rolling tire.

Resistance to Rolling and Sliding

Journal of Fluids Engineering, 1958
Abstract In general a single “coefficient of friction” is inadequate to define the fractional resistance between contacting bodies. It is necessary to know both the inclination of the resultant force line and the offset of this line from the theoretical point of contact.

Fundamentals of Rolling Resistance

Rubber Chemistry and Technology, 2001
Abstract Increasing pressure over the last three decades to improve vehicle fuel economy and decrease emissions along with a strong sense of environmental stewardship has driven the tire and rubber industries to reduce tire rolling resistance.

The Equations of the Rolling Resistance of a Tire Rolling on a Drum

Tire Science and Technology, 2008
Abstract This article attempts to write a mechanical justification of the ISO 18164 norm from a mathematical point of view. There are only minor differences between the final equations and the ones used in the norm. Indeed, this work is a formal derivation of what is already known.

FRICTION AND ROLLING RESISTANCE COEFFICIENTS OF FIG

Acta Horticulturae, 1998
The coefficients of friction and rolling resistance on various surfaces have great importance for designing agricultural machinery. In this research, two different methods were used. Rolling resistance or maximum angle of stability appearing during the rolling of fruits was measured on an inclined plane.

Effect of Tyre Inflation Pressure on Rolling Resistance: Comparing the Values of Coefficient of Rolling Resistance and Rolling Resistance at Variable Tyre Inflation Pressure

SAE Technical Paper Series, 2019
<div class="section abstract"><span class="label">1. </span><div class="htmlview paragraph">Rolling resistance, is nothing but the rolling drag, is the force resisting the motion when a body rolls on a surface. It is mainly caused by non-elastic effects; that is, not all the energy needed for deformation of the wheel, roadbed ...

Strain resistance of steel during roll ingotless rolling

Russian Metallurgy (Metally), 2007
The variation of the strain resistance during roll ingotless rolling has been considered; this variation is found to depend on the ratio of the solidification-zone length to the plastic-deformation-zone length, which affects the strain and strain rate.

Rolling Resistance Calculation

2015
This chapter provides a means for estimating the rolling resistance coefficient of a wheel. This information has two uses: it can assist the designer in choosing among candidate wheels and bearings, and it provides rolling resistance coefficients to be used in energy consumption analysis.
