Application of model updating techniques to turbomachinery rotor components
(Sage, 2019-07-12)
Model updating techniques are commonly used to improve simulation accuracy. Experimental data of component testing under laboratory conditions are normally used to improve analytical predictions of that component under ...
Design, Construction and Testing of a Hydraulic Power Take-Off for Wave Energy Converters
(MDPI, 2012-06)
This paper presents the construction, mathematical modeling and testing of a scaled universal hydraulic Power Take-Off (PTO) device for Wave Energy Converters (WECs). A specific prototype and test bench were designed and ...
Structural Synthesis of 3-DoF Spatial Fully Parallel Manipulators
(Intech Europe, 2014-07-16)
In this paper, the architectures of three degrees of freedom (3-DoF) spatial, fully parallel manipulators (PMs), whose limbs are structurally identical, are obtained systematically. To do this, the methodology followed ...
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 ...
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 ...
Optimization of Planar Mechanisms by using a Minimum Distance Function
(Elsevier, 2019-08)
The paper examines the application of a general minimum distance error function to the
dimensional kinematic synthesis of bidimensional mechanisms. The minimum distance ap-
proach makes it possible to solve the problem ...
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 ...
