Wear And Friction Evaluation Of Different Tool Steels For Hot Stamping
(Hindawi, 2018-03-26)
The aim of this work is to investigate the durability of tool steels for hot stamping by comparing the wear resistance of three hot work tool steels. Friction and wear behaviours of different tool steels sliding against a ...
Development of a Test-Bench for the Accurate Positioning of Scintillation Detector Modules for Medical Imaging Applications
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2018)
When assessing the impact of novel concepts of scintillation block detectors for PET tomography by measuring the performance of single modules, or one module in coincidence with another, it is not trivial to translate the ...
Prediction of moulds wear in high pressure die casting and plastic injection moulding
(2017-07-14)
En esta tesis doctoral se han abordado los principales mecanismos de desgaste que aparecen en los moldes de inyección de plástico y aluminio. Ambos consisten en inyectar a alta temperatura, presión y velocidad un fluido ...
A Proposal for a Formula of Absolute Pole velocities between Relative Poles
(Elsevier, 2017-04-10)
In this paper is proposed a vectorial equation that relates the absolute pole velocities of three moving rigid
bodies with a planar motion of general type. From this equation, it is possible to obtain a relation between ...
Control Distribution of Partially Decoupled Multi-level Manipulators with 5 DOFs
(Cambridge University Press, 2017-02-01)
Multi-level manipulators are those mechanisms in which two or more levels,
that de ne the main chain of the manipulator, are joined in parallel to
each other. Besides, each level is linked to the base in parallel by ...
Mechatronic Model Based Jerk Optimization in Servodrives with Compliant Load
(Springer Nature Switzerland AG, 2018-08-02)
The aim of this work is to develop a mechatronic model for servodrives that move a compliant load, which is the case of large heavy machine tools. The model integrates the dynamics of the motor, transmission chain and ...
Evaluation of the Bond-to-Concrete Properties of GFRP Rebars in Marine Environments
(MDPI, 2018-10-08)
Increased traffic in combination with growing environmental impacts have led to the accelerated degradation of built infrastructure. In reinforced concrete structures, the corrosion of steel reinforcement is the predominant ...
Wear Mechanisms and Wear Model of Carbide Tools during Dry Drilling of CFRP/TiAl6V4 Stacks
(MDPI, 2019-09-04)
The present contribution on tool wear during the drilling of carbon fiber composite materials (CFRP)/Ti stacks intends to determine (i) if the adhesion of titanium to carbide is mechanical or chemical, (ii) the possible ...
A robot for welding inspection in offshore mooring chains
(Springer, 2018-08-31)
In this paper, the authors present the CIRUS robot. This automatic system uses a combination of pulse-echo and pitch and catch ultrasonic strategies for the inspection of the welded area of mooring chain links in an automatic ...
