A contact mechanics study of 3D frictional conformal contact
(Elsevier, 2018-03)
A contact mechanics study of three-dimensional conformal contact with friction is presented, based on numerical calculations with Finite Element models and an extension of Kalker's exact contact theory which takes into ...
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 ...
Advanced Manufacturing Centres, Practical Model to Boost Technology Transfer in Manufacturing
(MDPI, 2019-09)
Establishing collaboration strategies with interdisciplinary networks in research is a crucial success factor for the companies in any sector, especially in manufacturing for aeronautics. In the aeronautical supply chain, ...
Estudio de las proteínas desde una perspectiva biocinemática: estado del arte
(Publicaciones DYNA, 2019-09-01)
Las proteínas son las macromoléculas encargadas de llevar a cabo la gran mayoría de las funciones vitales que los seres vivos requieren para su existencia. Estas macromoléculas, las cuales se asemejan a pequeños mecanismos ...
Drilling Process in γ-TiAl Intermetallic Alloys
(MDPI, 2018-11-26)
Gamma titanium aluminides (gamma-TiAl) present an excellent behavior under high temperature conditions, being a feasible alternative to nickel-based superalloy components in the aeroengine sector. However, considered as a ...
Optimum dimensional synthesis using GIMSYNT software
(Springer, 2019-06-14)
In the field of mechanism design, optimum dimensional synthesis
plays a significant role. Focusing on path generation synthesis, the designer has
to find the most adequate mechanism capable of tracing a trajectory as ...
Dynamics and mechanical vibrations. Complementing the theory with virtual simulation and experimental analysis
(Springer, 2018-09-21)
The purpose of the present work is to show how the complex theory in subjects related to
Mechanism and Machine Theory can be reinforced with some practicals in which the students can perform
virtual simulation of the ...
Prediction Methods and Experimental Techniques for Chatter Avoidance in Turning Systems: A Review
(MDPI, 2019-11)
The general trend towards lightweight components and stronger but difficult to machine materials leads to a higher probability of vibrations in machining systems. Amongst them, chatter vibrations are an old enemy for ...
Hole Making by Electrical Discharge Machining (EDM) of -TiAl Intermetallic Alloys
(MDPI, 2018-07)
Due to their excellent strength-to-weight ratio and corrosion and wear resistance, gamma-TiAl alloys are selected for aerospace and automotive applications. Since these materials are difficult to cut and machine by ...
Improving Stability Prediction in Peripheral Milling of Al7075T6
(MDPI, 2018-08)
Chatter is an old enemy to machinists but, even today, is far from being defeated. Current requirements around aerospace components call for stronger and thinner workpieces which are more prone to vibrations. This study ...
