Design, Construction and Testing of a Hydraulic Power Take-Off for Wave Energy Converters
(MDPI, 2012-06)
This paper presents the construction, mathematical modeling and testing of a scaled universal hydraulic Power Take-Off (PTO) device for Wave Energy Converters (WECs). A specific prototype and test bench were designed and ...
Effect of mounting misalignments on the tribological behaviour of elastomeric seals: analytical predictive models and experimental validation
(2016-07-14)
La presente tesis aborda el estudio del efecto de las excentricidades de montaje de ejes en el comportamiento tribológica de juntas elastoméricas, contribuyendo así a la escasez de estudios existentes relacionados con la ...
Structural Synthesis of 3-DoF Spatial Fully Parallel Manipulators
(Intech Europe, 2014-07-16)
In this paper, the architectures of three degrees of freedom (3-DoF) spatial, fully parallel manipulators (PMs), whose limbs are structurally identical, are obtained systematically. To do this, the methodology followed ...
Dynamic comparison of different types of slab tracks and ballasted track using a flexible track model
(Sage Publications, 2011-11)
The dynamic performance of a ballasted track and three types of slab tracks is analysed and compared by means of a comprehensive dynamic model of the train-track system, generated using two commercial analysis software ...
A rational fraction polynomials model to study vertical dynamic wheel-rail interaction
(Elsevier, 2012-04)
This paper presents a model designed to study vertical interactions between wheel and rail when the wheel moves over a rail welding. The model focuses on the spatial domain, and is drawn up in a simple fashion from track ...
Design of an optimised wheel profile for rail vehicles operating on two track gauges
(Taylor & Francis, 2013-01)
This paper sets out an optimum synthesis methodology for wheel profiles of railway vehicles in order to secure good dynamic behaviour with different track configurations. Specifically, the optimisation process has been ...
Kontaktuaren zenbakizko simulazioa artezketan
(2017-01-13)
Artezketan eragiten duten fenomenoak, harriaren eta piezaren arteko kontaktu-baldintzen naturarekin eta horien bilakaerarekin lotura zuzena dute. Kontaktu-eremuaren definizioak funtsezko garrantzia dauka artezketa-tenperaturen, ...
Virtual Sensors for On-line Wheel Wear and Part Roughness Measurement in the Grinding Process
(MDPI, 2014-05)
Grinding is an advanced machining process for the manufacturing of valuable complex and accurate parts for high added value sectors such as aerospace, wind generation, etc. Due to the extremely severe conditions inside ...
SEM and EDS Characterisation of Layering TiOx Growth onto the Cutting Tool Surface in Hard Drilling Processes of Ti-Al-V Alloys
(Hindawi Publishing Corporation, 2011)
Scanning electron microscopy (SEM) has been used to identify and analyse the secondary adhesion effect precursors formed during
the dry drilling processes of Ti-6Al-4V alloy over the rake face and flute of the drilling ...
Modelling rail corrugation with specific track parameters focusing on ballasted track and slab track
(Taylor & Francis, 2011-11)
The objective of this paper is to compare 3 types of track (high performance ballasted track, STEDEF and AFTRAV) from the corrugation growth point of view. This work has considered different vehicle speeds and track ...
