An ad-hoc fretting wear tribotester design for thin steel wires
Llavori, Inigo; Zabala, Alaitz; Tato, Wilson; Aginagalde, Andrea; Gómez Rodríguez, Xabier (EDP Sciences, 2018)Steel wire ropes experience fretting wear damage when the rope runs over a sheave promoting an oscillatory motion between the wires. Consequently, wear scars appear between the contacting wires leading to an ... -
An all-in-one numerical methodology for fretting wear and fatigue life assessment
Llavori, Inigo; Tato, Wilson; Gómez Rodríguez, Xabier (Gruppo Italiano Frattura, 2016)Many mechanical components such as, bearing housings, flexible couplings and spines or orthopedic devices are simultaneously subjected to a fretting wear and fatigue damage. For this reason, the combined study on a single ... -
Development of a Modular Fretting Wear and Fretting Fatigue Tribometer for Thin Steel Wires: Design Concept and Preliminary Analysis of the Effect of Crossing Angle on Tangential Force
Llavori, Inigo; Zabala, Alaitz; Tato, Wilson; Gómez Rodríguez, Xabier (MDPI AG, 2019)This work presents the design of a modular ad-hoc fretting fatigue and fretting wear tribotester for thin steel wires. The working principles of the diffrent modules are described, such as the displacement and contact ... -
Development of a novel method to characterize mean surface peak curvature as a signature of tribological performance of dental implant surfaces
Zabala, Alaitz; Aginagalde, Andrea; Llavori, Inigo; Tato, Wilson (IOP Publishing, 2020)The integrity of dental implant surfaces might be compromised during surgical insertion. Wear and topographical modifications can occur during implant insertion, which can potentially have clinical implications. Accordingly, ... -
Faktore klimatikoen degradazioaren efektua igogailuetako kable-polea trakzio sistemaren adherentzian
Barayazarra Benitez, Nerea; Zabala, Alaitz; Pecharroman Eizaguirre, Lander; Tato, Wilson; Aginagalde, Andrea (Tecnalia, 2021)Igogailuak trakzionatzeko existitzen diren hainbat metodoen artean kable eta polea bidezko trakzio-sistema oso arrunta da. Trakzio-sistema honetan kablearen eta polearen arteko itsaspenak berebiziko garrantzia du, eta ... -
Impact of surface roughness on the coefficient of friction of polymer-on-polymer contacts for deflection pulley-rope systems in the lift industry
Guinea, Ainhoa; Aginagalde, Andrea; Tato, Wilson; Llavori, Inigo; Zabala, Alaitz (Springer, 2024)The coefficient of friction (CoF) between the deflection pulley and rope in a lift strongly affects the life span of the rope. Although surface roughness is a key factor affecting the metallic pulley–rope CoF, its effect ... -
Surface integrity of additive manufacturing parts: a comparison between optical topography measuring techniques
Tato, Wilson; Llavori, Inigo; Aginagalde, Andrea; Zabala, Alaitz (Elsevier B.V., 2020)Additive Manufacturing (AM) presents significant industry-specific advantages allowing the creation of complex geometries and internal features that cannot be produced using conventional manufacturing processes. However, ... -
The use of areal surface topography characterisation in relation to fatigue performance
Zabala, Alaitz; Llavori, Inigo; Tato, Wilson; Aginagalde, Andrea; Gómez Rodríguez, Xabier (EDP Sciences, 2018)Although the effect of surface topography on fatigue life is widely accepted, the underlying role of surface roughness from first principles is still poorly understood. Currently approaches which consider the ...
