Laboratory Measurement of Rolling Resistance Coefficient under Different Conditions
Hungarian Journal of Industry and Chemistry, 2023 The aim of our research was to design and construct a measuring device that can determine the rolling resistance coefficient (RRC) under laboratory conditions. The measuring device has a drum arrangement, and the RRC was measured on two different model surfaces. The deceleration method was used to investigate the dependence of RRC on compression force,

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.

The impact of wheelchairs driving support systems on the rolling resistance coefficient
IOP Conference Series: Materials Science and Engineering, 2020 Abstract The 21stcentury is characterized by an increase in the obesity of society, including people with disabilities. The increase in the weight of people in wheelchairs requires them to have more power to drive these types of vehicles.

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.

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 ...

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.

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.

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 ...
