Dynamic optimization of track components to minimize rail corrugation
(Elsevier, 2009-01)
In this paper, the influence on corrugation of the most significant track parameters has been examined. After this parametric study, the optimization of the track parameters to minimize the undulatory wear growth has been ...
A comprehensive method for the elastic calculation of the two-point wheel-rail contact
(Taylor & Francis, 2006)
This work shows the method developed to solve the wheel-rail contact problem via a look-up table with a three-dimensional elastic model. This method enables introduction of the two contact point effect on vehicle movement ...
Deep Learning-Based Feature Extraction of Acoustic Emission Signals for Monitoring Wear of Grinding Wheels
(MDPI, 2022-09-13)
Tool wear monitoring is a critical issue in advanced manufacturing systems. In the search for sensing devices that can provide information about the grinding process, Acoustic Emission (AE) appears to be a promising ...
The patents in the introduction of reinforced concrete in Spain: "Alhondiga de Bilbao" case study
(Instituto de Ciencias de la Construcción Eduardo Torroja, 2014-06)
Reinforced concrete structures are introduced in Spain mainly by French influence. This happens in the late nineteenth century, following the scheme operating through proprietary systems prevailing in Europe. Systems ...
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 ...
Fiber-reinforcement and its effects on the mechanical properties of high-workability concretes manufactured with slag as aggregate and binder
(Elsevier, 2021-11)
[EN]The feasibility of manufacturing fiber-reinforced concretes of high workability through additions of high volumes of electric arc furnace steel slag is evaluated in this paper, using sustainable binders with ground ...
Approximating the influence coefficients of non-planar elastic solids for conformal contact analysis
(Elsevier, 2021-02)
The exact contact theory is an efficient alternative to the more general yet computationally expensive Finite Element Method for the detailed study of elastostatic contact problems. For its application in conformal contact ...
An active/passive joint for reconfiguration applications
(Springer, 2019-09-07)
In this paper, an active/passive reconfigurable 2R joint is presented. Direct and inverse kinematic problems and the force transmission are considered. The advantages of the current design show its superiority with respect ...
Estrategias mecánicas de las plantas arborescentes: enseñanzas estructurales de los árboles
(Universidad de Tarapacá, 2017-09)
Los árboles son los seres vivos más grandes que jamás han poblado la Tierra, pudiendo tener más de cien metros de altura, masas de varios miles de toneladas y alcanzar edades de varios miles de años. Para conseguirlo, entre ...
Design, characterization and experimental testing of two novel reconfigurable joints
(2022-03-11)
This Thesis focuses on the conception and design of joints to be used in reconfigurable parallel manipulators. A set of different joint designs was proposed and subjected to characteristics analysis in order to select the ...
