DETERMINATION OF THE ROLLING RESISTANCE COEFFICIENT UNDER DIFFERENT TRAFFIC CONDITIONS
Facta 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.

Predicting the wheel rolling resistance regarding important motion parameters using the artificial neural network [PDF]
Journal of Agricultural Machinery, 2016 Introduction: Rolling resistance is one of the most substantial energy losses when the wheel moves on soft soil. Rolling resistance value optimization will help to improve energy efficiency.

The Effect of Tread Pattern Tires on Hard Compound Coefficient Rolling Resistance
Journal 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
Nauka 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.

Chinese Journal of Mechanical Engineering, 2022 Laser cladding is a new surface repair method that can improve the wear and corrosion resistance of substrate surfaces. However, the cladding layer typically exhibits a rough surface, high hardness and large residual tensile stress, and thus requires ...

Determination of the rolling resistance coefficient of pneumatic wheel systems
AUTOBUSY – 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 ...

Jamming transition in a two-dimensional open granular pile with rolling resistance [PDF]
Papers in Physics, 2014 We present a molecular dynamics study of the jamming/unjamming transition in two-dimensional granular piles with open boundaries. The grains are modeled by viscoelastic forces, Coulomb friction and resistance to rolling.

Test Modes for Establishing the Tribological Profile under Slip-Rolling
Lubricants, 2020 The complex nature of slip-rolling contacts in many applications such as gear tooth flanks, rolling bearings, and heavy machinery often makes determining the friction and wear properties, as well as the fatigue resistance, of tribosystems difficult.
