(2021-03-04)
Esta tesis presenta el desarrollo de dos métodos de fatiga multiaxial basados en un modelo físico formulado a partir de consideraciones energéticas, siendo su ámbito de aplicación la fatiga de altos ciclos (HCF).El documento ...
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 ...
Predicción de fuerzas de corte y topografía superficial para la mejora de fresado de rotores de álabes integrados.
(2018-11-23)
Los rotores de álabes integrados consisten en discos rotativos con álabes fabricados en una sola pieza, los cuales están siendo cada vez más utilizados en los motores aeronáuticos debido a sus ventajas en cuanto a fiabilidad, ...
Sensitivity Analysis of Tool Wear in Drilling of Titanium Aluminides
(MDPI, 2019-03-06)
In the aerospace industry, a large number of holes need to be drilled to mechanically connect the components of aircraft engines. The working conditions for such components demand a good response of their mechanical ...
