Modelos de predicción del comportamiento a fatiga de componentes sometidos a tratamientos mecánicos2
(2018-06-29)
Esta Tesis presenta el estudio y comparación del efecto de los tratamientos mecánicos de shot-peening y bruñido de baja plasticidad en el comportamiento a fatiga de ciclos altos del acero 34CrNiMo6 de temple y revenido. ...
Dynamic Model of a Compliant 3PRS Parallel Mechanism for Micromilling
(Springer, 2016-09-10)
The objective of this work is to develop a manipulator of 5 degrees of freedom for micromilling. It consists of a XY stage under a 3PRS compliant parallel mechanism, obtaining the advantages of the compliant joints as are ...
Influence of PLA Filament Conditions on Characteristics of FDM Parts
(MDPI, 2018-08)
Additive manufacturing technologies play an important role in Industry 4.0. One of the most prevalent processes is fused deposition modelling (FDM) due to its versatility and low cost. However, there is still a lack of ...
Mechatronic modeling of a parallel kinematics multi-axial simulation table based on decoupling the actuators and manipulator dynamics
(Elsevier, 2016-11-07)
In this work a mechatronic model was developed for a parallel Multi-Axial Simulation Table (MAST) mechanism. The dynamics of the mechanism was obtained using the principle of energy equivalence and Boltzmann–Hamel equations. ...
Mechatronics of a ball screw drive using a N degrees of freedom dynamic model
(Springer, 2017-10)
High performance position control in machine tools can only be achieved modelling the dynamic behavior of the mechatronic system composed by the motor, transmission and control during the design stage. In this work, a ...
Mean Stress Effect on the Axial Fatigue Strength of DIN 34CrNiMo6 Quenched and Tempered Steel
(MDPI, 2018-04)
The present study consists of a theoretical and experimental investigation of the effect of axial mean stresses on the high cycle fatigue behaviour of DIN 34CrNiMo6 high strength steel in quenched and tempered conditions. ...
Experimental Validation of the Kinematic Design of 3PRS Compliant Parallel Mechanisms
(Elsevier, 2016-11)
In this paper, a procedure for the kinematic design of a 3-PRS compliant parallel manipulator of 3 degrees of freedom is proposed. First, under the assumption of small displacements, the solid body kinematics of the 3-PRS ...

Con el fin de aumentar la resistencia de las actuales herramientas empleadas en la estampación en caliente se proponen soluciones basadas en las tecnologías de deposición como alternativa a la construcción de herramientas ...
Analysis of the Process Parameter Influence in Laser Cladding of 316L Stainless Steel
(MDPI, 2018-09)
Laser Cladding is one of the leading processes within Additive Manufacturing technologies, which has concentrated a considerable amount of effort on its development. In regard to the latter, the current study aims to ...
Retained Austenite Control for the Soft Machining of High-Hardness Tool Steels
(MDPI, 2018-07-23)
Most high-hardness tool steels comprising forming dies require expensive finish machining operations to compensate for the dimensional distortion and surface oxidation caused by the die heat treatment. Precipitation-hardening ...
