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 ...
Translational parallel manipulator with Pa2 kinematic joints
(Springer, 2016-10-01)
The kinematic pair Pa2 is composed of two interlinked parallelograms. It has two degrees of freedom that generate a translational plane variable with position. It has a structure different from the PaPa pair, which is ...
Multi-Criteria Decision-Making Method for Sustainable Energy-Saving Retrofit Façade Solutions
(MDPI, 2021-11-27)
The increasing energy consumption levels of buildings within Europe call for controlled consumption and improvements to energy savings and efficiency and effective energy efficiency regulations. However, many aging and ...
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 ...
Modelización de la relajación de tensiones residuales introducidas por el tratamiento mecánico de shot-peening para la mejora de la resistencia a fatiga del acero DIN 34CrNiMo6
(2022-11-18)
Se aplica al acero DIN 34CrNiMo6 un tratamiento mecánico de shot-peening con el objetivo de mejorar su resistencia a fatiga axial. Se obtiene una mejora del 22% respecto a piezas únicamente mecanizadas y del 3,5% respecto ...
Hybrid manufacturing of complex components: Full methodology including laser metal deposition (LMD) module development, cladding geometry estimation and case study validation
(Elsevier, 2022-11)
To optimize and satisfy current industrial requirements, during the last decade new alternatives to conventional manufacturing processes are implemented into conventional machines, leading to multitasking machines. Especially ...
