Determination of the rolling resistance coefficient of pneumatic wheel systems

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 ...

Jamming transition in a two-dimensional open granular pile with rolling resistance [PDF]

open access: yesPapers 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.

Corrosion Resistance and Tribological Properties of Laser Cladding Layer of H13 Die Steel Strengthened by Ultrasonic Rolling

open access: yesChinese 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 ...

Test Modes for Establishing the Tribological Profile under Slip-Rolling

open access: yesLubricants, 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.

DEM investigation on characteristics of rolling resistance for modelling particle shape

open access: yesEPJ Web of Conferences, 2017
To examine the capability of rolling resistance to model the effects of particle shape, two sets of samples, composed of binary clumped particles and circular particles with rolling resistance, are tested in DEM simulation.

Research on Thickness Defect Control of Strip Head Based on GA-BP Rolling Force Preset Model

open access: yesMetals, 2022
Due to the inaccuracy of the preset rolling force of cold rolling, there is a severe thickness defect in the strip head after cold rolling due to the flying gauge change (FGC), which affects the yield of the strip.

Data Driven Methods for Finding Coefficients of Aerodynamic Drag and Rolling Resistance of Electric Vehicles

open access: yesWorld Electric Vehicle Journal, 2023
This research investigated an alternate method for establishing the complex coefficients used in an electric vehicle’s mathematical energy consumption model. While other methods for creating electric vehicle energy models exist, it would be beneficial to have a rapid and inexpensive technique that remains accurate. Producing a mathematical energy model
