Identification of Rolling Resistance Coefficients for Aircraft Tires on Unsurfaced Airfields

Journal of Aircraft, 2007
The 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, 2013
The 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

METHOD OF MEASURING SPECIFIC PRESSURES OF TRACTOR WHEELS ON THE SOIL AND DETERMINATION OF ROLLING RESISTANCE COEFFICIENT

Вестник Бурятской государственной сельскохозяйственной академии имени В. Р. Филиппова, 2023
В условиях интенсификации сельскохозяйственного производства мобильные энергетические средства за счет многократного воздействия на почву приводят к переуплотнению почвы и снижению ее плодородия. При осуществлении основных технологических операций почва выступает в роли несущего основания для колес тракторов, оказывающих на нее высокое механическое ...

A Cost-Effective Alternative to Moving Floor Wind Tunnels in Order to Calculate Rolling Resistance and Aerodynamic Drag Coefficients

SAE International Journal of Passenger Cars - Mechanical Systems, 2014
<div class="section abstract"><div class="htmlview paragraph">This study investigates the practicality of vehicle coast down testing as a suitable replacement to moving floor wind tunnel experimentation. The recent implementation of full-scale moving floor wind tunnels is forcing a re-estimation of previous coefficient of drag ...

On-Road Fuel Consumption Testing to Determine the Sensitivity Coefficient Relating Changes in Fuel Consumption to Changes in Tire Rolling Resistance

Tire Science And Technology, 2013
ABSTRACT: Tire rolling resistance is one of the primary forces opposing motion on passenger vehicles. New regulations appearing around the world will provide information on tire rolling resistance to consumers. The linear relationship between fuel savings and rolling resistance has been previously demonstrated.

Contribution of rolling resistance to the drag coefficient of short-span cylinders freely rolling on a rough inclined surface

Abstract: This study examines the contribution of rolling resistance to the drag coefficient of finite-span cylinders rolling freely without slipping on a rough inclined surface in a quiescent fluid. Experiments are performed to obtain the variation of the time-mean drag coefficient against the varied roughness of the panel.
