Mechatronics of a ball screw drive using a N degrees of freedom dynamic model
(Springer, 2017-10)
High performance position control in machine tools can only be achieved modelling the dynamic behavior of the mechatronic system composed by the motor, transmission and control during the design stage. In this work, a ...
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 ...
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 ...
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 ...
