Vertical Vibration Model for Unsteady Lubrication in Rolls-Strip Interface of Cold Rolling Mills
Advances in Mechanical Engineering, 2012 According to the vertical vibration phenomena existing in cold rolling mills, the unsteady lubrication mechanism in roll gap and its influence to rolling stability was chosen as the case for analysis.

THE THEORETICAL FOUNDATIONS OF VIBRATION DAMPERS BY ROLLING FRICTION
Nauka ta progres transportu, 2015 Purpose. There are some unresolved issues in vibration damping – the lack of engineering calculations for the vibration dampers by rolling friction; the absence of evidence of their application appropriateness.

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.

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation
Advanced Materials, EarlyView.Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Rolling friction and bistability of rolling motion
, 2005 The rolling motion of a rigid cylinder on an inclined flat viscous surface is investigated and the nonlinear resistance force against rolling, $F_R(v)$, is derived. For small velocities $F_R(v)$ increases with velocity due to increasing deformation rate of the surface material.

Advanced Materials, EarlyView.A multidimensional molecular strategy optimizes the tribonegative layer by electrospinning PVDF‐HFP for dipole alignment and crystallinity, followed by 2D borophene doping to enhance conductivity and charge trapping. Integrated with Nylon‐66 nanofibers, the composite device delivers a record sensitivity of 53.8 ± 1.2 V kPa−1 at 3 Hz, enabling ultra ...

Disk on Disk Test of Gear Pair Power Losses [PDF]
Tribology in Industry, 2010 This paper presents the research of friction in gear pairs by using tribometer that provides diskon-disk contact. When gear teeth mesh, there is a combination of sliding friction and rolling friction, and in that, the values of sliding and rolling ...
