Comments on Rolling Resistance
Journal of Tribology, 1994Rolling resistance model, developed based on rigid body assumption, is further analyzed in this paper using a simplified analytical model and experimental results. The analysis leads to the conclusion that the effect of the reaction forces is equivalent to a resultant having the point of contact located outside the zone of contact.

ROLLING RESISTANCE FORCE MEASURING
SAE Technical Paper Series, 2007<div class="htmlview paragraph">The purpose of this work is to make a system for to measure the rolling force using a tire and a moving belt. The starting point is to establish study arguments as tire pressure, camber, divergence, convergence and steering knuckle force. The low cost made equipment allows the angles adjustment, and applied load on

Strain resistance of steel during roll ingotless rolling
Russian Metallurgy (Metally), 2007The 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.

Thermal-fatigue resistant work rolls for hot rolling mills
Materials Testing, 2019Abstract Cyclic temperature changes in the working layer of a roll during hot rolling cause thermal stress which leads to damage on the surface layer of the roll due to thermal fatigue. The pre-conditions of crack initiation are described.

Rolling Resistance Calculation
2015This 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.

Rolling Resistance of a Skateboard
Volume 14: Safety Engineering, Risk, and Reliability Analysis, 2020Abstract Skateboards have been used as a means of transportation and extreme sports for decades. The forensic analysis of skateboard-related accidents requires knowledge of the kinematic characteristics of the skater-skateboard and skateboard-ground interactions to aid in the investigative process.

Laboratory Evaluation of Rolling Resistance
2021This paper presents a laboratory test method to characterize the relationship between rolling resistance and macrotexture of road surfaces. Description of the testing (machine, samples, protocol) is provided. Results are comparable to those obtained by instrumented trailers on road surfaces with similar macrotexture.

The rolling resistance (RR) of a tire depends on three factors: (i) the energy loss of rubber and reinforcements due to the cyclic deformation of the rolling tire, (ii) frictional energy in the contact area and (iii) the air resistance of the tire.
