4P operational harmonic and blade vibration in wind turbines: a real case study of an active yaw system and a concrete tower
Torres Elizondo, Antonio; Gil Soto, José Javier; Plaza Puértolas, Aitor
; Aginaga García, Jokin (Elsevier, 2024)
Artículo / Artikulua 
This study aims to comprehensively investigate the impact of mechanical loads on the performance and lifetime of wind turbines, with particular emphasis on blade vibration at the 4P operational harmonic. Experiments and ... -
Dynamic considerations of heel-strike impact in human gait
Ros Ganuza, Javier ; Font-Llagunes, Josep M.; Plaza Puértolas, Aitor ; Kövecses, József (Springer, 2015)
Artículo / Artikulua
Based on the impulsive-dynamics formulation, this article presents the analysis of different strategies to regulate the energy dissipation at the heel-strike event in the context of human locomotion. For this purpose, a ... -
Inertia transfer concept based general method for the determination of the base inertial parameters
Ros Ganuza, Javier ; Plaza Puértolas, Aitor ; Iriarte Goñi, Xabier ; Aginaga García, Jokin (Springer, 2015)
Artículo / Artikulua
This paper presents a new algorithm to obtain the symbolic expressions of any of the possible base inertial parameter sets of a multibody system. Based on the ¿inertia transfer concept¿, a procedure is proposed to write a ... -
Instantaneous amplitude and phase signal modeling for harmonic removal in wind turbines
Zivanovic, Miroslav ; Plaza Puértolas, Aitor ; Iriarte Goñi, Xabier ; Carlosena García, Alfonso (Elsevier, 2023)
Artículo / Artikulua
We present a novel approach to harmonic disturbance removal in single-channel wind turbine acceleration data by means of time-variant signal modeling. Harmonics are conceived as a set of quasi-stationary sinusoids whose ... -
Kinematic design of a new four degree-of-freedom parallel robot for knee rehabilitation
Aginaga García, Jokin ; Iriarte Goñi, Xabier ; Plaza Puértolas, Aitor ; Mata, Vicente (ASME, 2018)
Artículo / Artikulua
Rehabilitation robots are increasingly being developed in order to be used by injured people to perform exercise and training. As these exercises do not need wide range movements, some parallel robots with lower mobility ... -
Mode-displacement method for structural dynamic analysis of bio-inspired structures: a palm-tree stem subject to wind effects
Plaza Puértolas, Aitor ; Vargas-Silva, G.; Iriarte Goñi, Xabier ; Ros Ganuza, Javier (Taylor & Francis, 2022)
Artículo / Artikulua
Biological materials (orthotropic materials), like wood, can offer good mechanical properties with a minimum amount of material, making their internal structure the suitable one to be applied on bio-inspired structures. ... -
Symbolic multibody methods for real-time simulation of railway vehicles
Ros Ganuza, Javier ; Plaza Puértolas, Aitor ; Iriarte Goñi, Xabier ; Pintor Borobia, Jesús María (Springer, 2018)
Artículo / Artikulua
In this work, recently developed state-of-the-art symbolic multibody methods are tested to accurately model a complex railway vehicle. The model is generated using a symbolic implementation of the principle of virtual ... -
Trayectorias de máxima rigidez de un robot redundante actuando como soporte en el mecanizado de paredes delgadas
Aginaga García, Jokin ; García Cuesta, Iván; Iriarte Goñi, Xabier ; Plaza Puértolas, Aitor (Universitat Politècnica de València, 2023)
Artículo / Artikulua
La precisión de un robot está ligada a su rigidez. En comparación con la máquina herramienta tradicional, los robots industriales tienen un gran espacio de trabajo como ventaja, pero una rigidez reducida como desventaja. ... -
Triaxial accelerometer based azimuth estimator for horizontal axis wind turbines
Plaza Puértolas, Aitor ; Ros Ganuza, Javier ; Gainza, Gorka; Fuentes Lárez, José David (Elsevier, 2023)
Artículo / Artikulua
One of the elements that receives the greatest stresses is the main shaft. Its damage is directly related to the cyclical nature of its rotational motion. However, the vast majority of horizontal axis wind turbines (HAWT) ... -
Ultra-low frequency multidirectional harvester for wind turbines
Castellano Aldave, Jesús Carlos; Carlosena García, Alfonso ; Iriarte Goñi, Xabier ; Plaza Puértolas, Aitor (Elsevier, 2023)
Artículo / Artikulua
In this paper we propose, and demonstrate through a prototype, a completely novel device able to harvest mechanical energy from the multidirectional vibrations in a wind turbine, and convert it into electrical, to power ... -
A unified analytical disk cam profile generation methodology using the Instantaneous Center of Rotation for educational purpose
Iriarte Goñi, Xabier ; Bacaicoa Díaz, Julen ; Plaza Puértolas, Aitor ; Aginaga García, Jokin (Elsevier, 2024)
Artículo / Artikulua
Cam design is a fundamental part of the Mechanism and Machine Theory (MMT) and is included in the vast majority of MMT books. Cam profile design is usually determined with graphical and analytical methods. Graphical methods ...
