A robot for non-destructive testing weld inspection of offshore mooring chains
(SAGE Publications Inc., 2018-05-09)
Welding flaw detection is a key step in manufacturing many components. In offshore chains, every link is manufactured from a steel bar that is bent and the ends joined by flash butt welding. Ultrasonic inspection of the ...
Failure-Analysis Based Redesign of Furnace Conveyor System Components: A Case Study
(MDPI, 2019-08)
Any manufacturing equipment designed from scratch requires a detailed follow-up of the performance for the first units placed in service during the production ramp-up, so that lessons learned are immediately implemented ...
Application of model updating techniques to turbomachinery rotor components
(Sage, 2019-07-12)
Model updating techniques are commonly used to improve simulation accuracy. Experimental data of component testing under laboratory conditions are normally used to improve analytical predictions of that component under ...
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 ...
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 ...
Alternative experimental methods for machine tool dynamics identification: A review
(Elsevier, 2022-05-01)
An accurate machine dynamic characterization is essential to properly describe the dynamic response of the machine or predict its cutting stability. However, it has been demonstrated that current conventional dynamic ...
Un procedimiento para el diseño mecatrónico de manipuladores de cinemática paralela tipo compliant
(2022-05-27)
El objeto de este trabajo es desarrollar una metodología integral de diseño mecatrónico de mecanismos paralelos tipo compliant, es decir, cuyo movimiento se consigue gracias a la deformación de determinados puntos del ...
Cosserat thermo-mechanics under finite deformations: theory and finite element implementation
(2022-05-23)
The objective of this thesis is to propose a theory that is able to capture specific phenomena during machining operations on metals. Recent investigations proved that dislocations-driven mechanisms at molecular or atomic ...
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 ...
Metodología para el control del temple y el acabado de componentes de precisión endurecidos mediante grind-hardening
(2015-07-03)
El grind-hardening es una tecnología que aprovecha el calor generado durante el rectificado para generar un endurecimiento superficial de la pieza. De esta forma, el endurecimiento y acabado de la pieza pueden realizarse ...
