Determination of the symbolic base inertial parameters of planar mechanisms
The inertial information of a planar mechanical system is characterised using 4 inertial parameters per solid. Due to the kinematic constraints, this parametrisation turns out be redundant. In order to reduce the ... -
Instantaneous amplitude and phase signal modeling for harmonic removal in wind turbines
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
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 ... -
Mechanical sensitivity analysis of strain gauge configurations in the main shaft of wind turbines
Wind turbines are reaching their remaining useful life, thus it is important to guarantee the well status of its components. A common way to check the status is to measure the loads on the Low Speed Shaft with strain gauges, ... -
Mode-displacement method for structural dynamic analysis of bio-inspired structures: a palm-tree stem subject to wind effects
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. ... -
Modelado multiplataforma para el control de un sistema articulado
En el presente artículo se ha trabajado con las herramientas de simulación de sistemas mecánicos Gazebo y Simulink, realizando una interconexión entre ambos con el fin de desglosar la parte dinámica y cinemática de la parte ... -
On the convergence of a modal updating iterative method applied to a vibrating table for food transportation
This work focuses on the updating of the parameters of a Vibrating Table Multibody model. Modal Analysis has been done to obtain the experimental Modal Parameters of the System (natural frequencies (ωi), damping ratios ... -
Optimal strain gauge configurations for the estimation of mechanical loads in the main shaft of HAWT
In Structural Health Monitoring of wind turbines, measuring the mechanical loads is a key issue. The customary techniques for this task use a full-bridge strain gauge configuration to measure each of the six load components ... -
Optimal strain-gauge placement for mechanical load estimation in circular cross-section shafts
The customary electrical circuit configuration for estimating mechanical loads with strain gauges uses Wheatstone full- or half-bridges. For each mechanical load to be estimated, a dedicated bridge with two or four gauges has ... -
Robotic belt finishing with process control for accurate surfaces
The aerospace industry still relies on manual processes for finish applications, which can be a tedious task. In recent years, robotic automation has gained interest due to its flexibility and adaptability to provide ... -
Symbolic multibody methods for real-time simulation of railway vehicles
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
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. ... -
Ultra-low frequency multidirectional harvester for wind turbines
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 ...
