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 ...
Modelos para el análisis del comportamiento en servicio de rodamientos de vuelco de contacto angular de 4 puntos
(2017-02-01)
Los rodamientos de vuelco son rodamientos de grandes dimensiones utilizados comoelementos de orientación para aplicaciones sometidas a altas cargas, cuya velocidadde rotación es lenta y operan la mayoría de veces de manera ...
Kinematic Analysis of a Continuum Parallel Robot
(Springer, 2017)
Continuum Parallel Robots are mechanical devices with closed loops where kinematic pairs have been eliminated and motion is obtained by large deformations of certain elements. Most compliant mechanisms use notches in thick ...
Kinematic Analysis of a Flexible Tensegrity Robot
(Springer, 2017)
In the field of parallel kinematics few designs use highly deformable elements to obtain the end effector movement. Most compliant mechanisms rely on notches or shape changes to simulate a standard kinematic joint. In this ...
Performance of Gradient-Based Solutions versus Genetic Algorithms in the Correlation of Thermal Mathematical Models of Spacecrafts
(Hindawi, 2017)
The correlation of the thermalmathematical models (TMMs) of spacecrafts with the results of the thermal test is a demanding task in terms of time and effort. Theoretically, it can be automatized by means of optimization ...
Desarrollo de un sistema de optimización de forma para perfiles aerodinámicos mediante algoritmos genéticos
(2017-07-11)
La optimización de forma en fluidodinámica consiste en encontrar diseños de elementos mecánicos que den flujos con características óptimas. Físicamente se tiene un flujo que interactúa con ciertos elementos mecánicos sólidos ...
Eraikuntza sektoreko enpresen berrikuntza maila neurtzeko modelo baten garapena
(2017-03-24)
Eraikuntza sektorea ez da bere errendimendu berritzaileagatik bereizten eta historikoki bere eraginkortasun-ezagatik kritikatua izan da. Horrez gain, gaur egungo krisi-ondorengo eszenatoki zailak ehun produktiboaren eta ...
Virtual Sensor for Kinematic Estimation of Flexible Links in Parallel Robots
(MDPI, 2017-09)
The control of flexible link parallel manipulators is still an open area of research, endpoint trajectory tracking being one of the main challenges in this type of robot. The flexibility and deformations of the limbs make ...
Intelligent nozzle design for the Laser Metal Deposition process in the Industry 4.0
(Elsevier, 2017)
Laser Metal Deposition (LMD) is an AM (Additive Manufacturing) process that enables to build 3D geometries or enhance the surface properties of the base material by the generation of a coating. With the aim of integrating ...
Laser Metal Deposition enhancement by holistic simulation of powder mass flow and deposition into the melt pool
(2017-06-09)
En el presente trabajo de investigación se ha desarrollado una metodología para la mejora del proceso de aporte por láser mediante la modelización del mismo. El problema se ha abordado en diferentes pasos. Primero de todo, ...
