DETERMINATION OF THE ROLLING RESISTANCE COEFFICIENT UNDER DIFFERENT TRAFFIC CONDITIONS [PDF]

open access: yesFacta Universitatis, Series: Mechanical Engineering, 2020
In this paper, an experimental study of the determination of the rolling resistance coefficient is carried out. The experiment tests a total of six different types of vehicles and calculates the rolling resistance coefficient depending on the condition of the surface and the type of tires.

The Effect of Tread Pattern Tires on Hard Compound Coefficient Rolling Resistance [PDF]

open access: yesJournal of Mechanical Engineering, Science, and Innovation, 2022
Rolling resistance is the resistance of a wheel that will roll or rotate due to friction between the outer surface of the wheel and the track surface. This study aims to determine the effect of tread patterns on the coefficient of rolling resistance.

RELATIONSHIP BETWEEN ROLLING AND SLIP RESISTANCE IN ROLLING BEARINGS

open access: yesNauka ta progres transportu, 2016
Purpose. About one of the causes of slip rolling is known from the second half of the 19th century, it was believed that the slip resistance appears at the place of contact due to different speeds on the arc of contact.

Determination of the rolling resistance coefficient of pneumatic wheel systems [PDF]

open access: yesAUTOBUSY – Technika, Eksploatacja, Systemy Transportowe, 2019
The basic resistance during moving objects that are equipped with a circular system is rolling resistance. In objects powered by muscle power, such as: bicycles, wheelchairs, mobile machines, shelves and storage trolleys, the problem of rolling resistance limitation is more important than in the case of structures powered by engines characterized by a ...
