Friction torque in four-point contact slewing bearings: applicability and limitations of current analytical formulations
(Elsevier, 2017-11)
The friction torque is a key parameter in the design of slewing bearings. The most challenging issue in its calculation
resides in the modelling of rolling element contact mechanics. In this manuscript two models for the ...
Friction torque in four contact point slewing bearings: Effect of manufacturing errors and ring stiffness
(Elsevier, 2017-02-24)
This work outlines a procedure for the determination of the interferences between balls and raceways in four contact
point slewing bearings due to manufacturing errors. The procedure is applied to a particular case and ...
A novel experimental procedure to determine the cohesive law in ENF tests
(Elsevier, 2019-01)
This study presents a novel method to determine the mode II cohesive law of unidirectional carbon fiber reinforced polymer laminates, employing the End Notched Flexure (ENF) test.
The fracture toughness in mode II (G) ...
Efficient assembly of bolted joints under external loads using numerical FEM
(Elsevier, 2018-05-16)
Several factors can cause leakages in a bolted flange connection, external loads being the
most important one. External loads such as those produced by misalignment introduce an
external axial load combined with a bending ...
Analysis of the DCB test of angle-ply laminates including residual stresses
(Elsevier, 2017-03-14)
[ES] Se propone un nuevo método para obtener la tasa de liberación de energía mediante la prueba de doble viga en voladizo para laminados de capas angulares. Se estudian dos secuencias diferentes, simétrica y antisimétrica. ...
Study of the structural behaviour and analytical characterization of wire-race slewing bearings
(2022-03-25)
La presente tesis doctoral tiene como objetivo presentar los últimos avances en el campo de los rodamientos de vuelco con pista de rodadura alámbrica (wire-race bearings). Debido a la escasa literatura científica disponible ...
A skid resistance prediction model for an entire road network
(Elsevier Ltd., 2020-11-30)
[EN]This article predicts the available minimum skid resistance in the road network of Biscay (Spain) with data collected in the summer season when friction values are at a minimum. Firstly, it was observed that pavement ...
An Improved Meshing Method for Shape Optimization of Aerodynamic Profiles Using Genetic Algorithms
(WILEY, 2008)
One of the basic problems in fluid dynamics shape optimization is mesh generation. When analysis is performed using the finite element method, meshes of sufficient quality need to be constructed automatically. This work ...
A feedforward controller for tuning laser cladding melt pool geometry in real time
(Springer, 2016-07-12)
In this paper, a feedforward proportional-integral (PI) controller is developed to effectively control and tune the laser cladding melt pool geometry in real time. Width setpoint is included in the computer numerically ...
