Electrodynamic Wheel Magnetic Rolling Resistance

IEEE Transactions on Magnetics, 2017
In this paper the concept of magnetic rolling resistance (MRR) is introduced. The MRR is particularly useful when trying to characterize maglev devices that operate with a slip. Approaches to minimize the MRR for an electrodynamic wheel magnetic suspension device are discussed. MRR is calculated from the power losses and it is shown that by using MRR a

Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres

Advanced Engineering Materials, EarlyView.
This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.

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.

Preparation of Low Rolling Resistance Modified Asphalt and Analysis of Its Rolling Resistance and Viscoelasticity

Tehnicki vjesnik - Technical Gazette, 2021
R E T R A C T E D A R T I C L E Tire tread of running vehicles generates rolling resistance with the pavement, thereby influencing energy consumption. Thus, developing low rolling resistance pavement can improve the service function of tires. Common matrix asphalt and high module binder modifier (HMB-W) was used to obtain low rolling resistance of ...

Enhancing Strength and Electrical Conductivity in Al–Zr–Sc Conductor Alloys Through Sn and Sr Microalloying and Two‐Step Aging Treatment

Advanced Engineering Materials, EarlyView.
Trace additions of Sn and Sr combined with a two‐step aging treatment are shown to enhance the microstructure and performance of Al–Zr–Sc conductor alloys. Strength and electrical conductivity increase concurrently through accelerated precipitation of fine Al3(Sc, Zr) precipitates and improved dislocation resistance, offering a cost‐effective pathway ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Rolling Resistance of Pneumatic Tires [PDF]

Tire Science and Technology, 1978
Abstract Linear relations have been observed experimentally between tire equilibrium rolling resistance, tire load, and the reciprocal of tire inflation pressure. These variables are used to formulate a simple general expression for rolling resistance, and predictions made with this expression are compared with measured data.
