Optimización de procesos de recubrimiento para herramientas de corte. Tecnologías de recubrimiento, métodos de caracterización y optimización de las propiedades
(2015-11-20)
La aplicación de los recubrimientos PVD en herramientas de corte, es uno de los campos más importantes para su utilización. Actualmente los procesos de fabricación plantean retos de reducción de costes, mayor eficiencia, ...
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 ...
Chatter avoidance in the milling of thin floors with bull-nose end mills: Model and stability diagrams
(Elsevier, 2011-01)
The milling of thin parts is a high added value operation where the machinist has to face the chatter problem. The study of the stability of these operations is a complex task due to the changing modal parameters as the ...
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 ...
Correlación de modelos térmicos matemáticos de sistemas espaciales con ensayos térmicos mediante algoritmos genéticos.
(2018-04-06)
Las condiciones ambientales en el espacio exterior son muy extremas. Por ello cualquier equipo que es enviado al espacio cuenta con un sistema de control térmico (TCS) cuyo propósito es mantener los distintos componentes ...
Using nodal coordinates as variables for the dimensional synthesis of mechanisms
(Springer, 2018-06)
The method of the lower deformation energy has been successfully used for the synthesis of mechanisms for quite a while. It has shown to be a versatile, yet powerful method for assisting in the design of mechanisms. Until ...
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 ...
An efficient LDU algorithm for the minimal least squares solution of linear systems
(Elsevier, 2018-12-15)
The minimal least squares solutions is a topic of interest due to the broad range of applications of this problem. Although it can be obtained from other algorithms, such as the Singular Value Decomposition (SVD) or the ...
Insights into mechanism kinematics for protein motion simulation
(Biomed Central, 2014-06-12)
Background: The high demanding computational requirements necessary to carry out protein motion simulations make it difficult to obtain information related to protein motion. On the one hand, molecular dynamics simulation ...
