Texte intégralThe aim of this study is to improve the performances, in terms of memory space and computational time, of the current modelling of the Pellet-Cladding mechanical Interaction (PCI),complex phenomenon which may occurs during high power rises in pressurised water reactors. Among the mesh refinement methods - methods dedicated to efficiently treat local singularities - a local multi-grid approach was selected because it enables the use of a black-box solver while dealing few degrees of freedom at each level. The Local Defect Correction (LDC) method, well suited to a finite element discretisation, was first analysed and checked in linear elasticity, on configurations resulting from the PCI, since its use in solid mechanics is little widespread. Various strategies concerning the implementation of the multilevel algorithm were also compared. Coupling the LDC method with the Zienkiewicz-Zhu a posteriori error estimator in orderto automatically detect the zones to be refined, was then tested. Performances obtained on two-dimensional and three-dimensional cases are very satisfactory, since the algorithm proposed is more efficient than h-adaptive refinement methods. Lastly, the LDC algorithm was extended to nonlinear mechanics. Space/time refinement as well as transmission of the initial conditions during the remeshing step were looked at. The first results obtained are encouraging and show the interest of using the LDC method for PCI modelling

Texte intégralWe consider a defect correction method that combines a first-order upwinded difference scheme with a second-order central difference scheme for model singularly perturbed convection-diffusion problems in one and two dimensions on a class of Shishkin-Type meshes. In one dimension, the method is shown to be convergent uniformly in the diffusion parameter $\epsilon$ of second order in the discrete maximum norm. To analyze the two-dimensional case, we discuss several proof techniques for defect correction methods. For a special problem with constant coefficients on a piecewise uniform Shishkin-mesh we can show the second order convergence of the considered scheme, uniformly with respect to the diffusion parameter. Moreover the known stability properties and their impact on the convergence analysis of the considered differnce schemes are compiled. Some remarks on defect correction and finite elements conclude the theses. Numerical experiments support our theoretical results

Short-wave infrared (SWIR) hyperspectral image (HSI) provides detailed spectral information regardless of target detection applications in military or search and rescue. While most HSI tasks image a static scene by a push-broom scanner, here a liquid crystal tunable filter (LCTF) is mounted in front of a broad-band SWIR camera to take snapshots of dynamic scenes. Due to the optical defects in LCTF, the collected images have pattern of interference fringes (PIF), which causes spatial and spectral distortion and interferes the target recognition tasks. Therefore, the purpose of this study is to develop a correction algorithm to eliminate PIF in the spectral images, and improve the recognition accuracy. We experimentally investigated the cause of PIF, and found the cost of hardware solution is very high. Therefore, we turned to develop algorithmic solutions. By collecting the reference images with PIF only, we examined three correction methods: (1) Template-based elimination, which directly subtracts the reference from the collected image; (2) Two-point correction, which uses two referenced intensities to derive a linear curve to predict the original pixel intensities; (3) Polynomial fitting, which uses multiple reference intensities to derive a nonlinear curve to predict the original pixel intensities. We found the third method is the most effective. Their technical details and corresponding experimental results are documented in the thesis.

Texte intégralThis work is integrated in a project of development of a novel measurement device, the BMG-4 sensor, and its application in the calibration of industrial robots. The aim of the work is to define procedures and strategies that enable, through the BMG-4, to identify both geometric and compliance errors that are present in 6-axes serial industrial robots. The importance of accuracy and robot calibration as well as the problem of the suitability of most measurement systems to industrial environments is highlighted. Consequently, the BMG-4 is introduced as a solution that meets the demands of those conditions. A geometrical methodology is defined to determine the direction of a robot’s axis and to assess its accuracy. A protocol that allows to identify the real angular geometric parameters of the robot, as well as the offsets of some axes is presented. Then, a strategy is developed in order to be able to identify the compliances of the last five axes of the robot. All the tests are performed in an ABB IRB 6600 industrial robot. For axes 2 and 3, the maximum values obtained for inaccuracy are 0,062° and 0,229°, respectively. Also, the robot presents several considerable joints’ offsets errors. For axes 4 and 5 those values are −0,99° and 0,83°. The combined offset of axes 2 and 3 is −0,28°. The stiffness of axis 2 is determined, having an estimated value of 2,4 × 106 N.m/rad. Finally, a standard robot convention is proposed in order to correct the identified errors with a generalized compensation algorithm.
Este trabalho está integrado num projeto de desenvolvimento de um novo dispositivo de medição, o sensor BMG-4, e da sua aplicação na calibração de robôs industriais. O objetivo do trabalho é a definição de procedimentos e estratégias que permitem, através do BMG-4, identificar erros provenientes tanto da geometria como da flexibilidade das articulações do robô que estão presentes em robôs industriais de 6-eixos. A importância da precisão e da calibração robótica, bem como o problema da adequação da maioria dos sistemas de medição em ambientes industriais são destacados. Consequentemente, o BMG-4 é introduzido como uma solução que satisfaz essas condições. Uma metodologia geométrica é definida para determinar a direção do eixo de um robô e para avaliar a sua precisão. Um protocolo que permite identificar os parâmetros geométricos angulares reais do robô, bem como os offsets de alguns eixos, é apresentado. Em seguida, uma estratégia é desenvolvida de maneira a identificar os valores de rigidez dos últimos cinco eixos do robô. Todos os testes são realizados no robô industrial ABB IRB 6600. Para os eixos 2 e 3, os valores máximos obtidos para a análise da imprecisão são 0,062° e 0,229°, respectivamente. Além disso, o robô apresenta erros de offset consideráveis. Para os eixos 4 e 5 esses valores são −0,99° e 0,83°. O valor combinado dos eixos 2 e 3 é −0,28°. A rigidez do eixo 2 é determinada, tendo um valor estimado de 2,4 × 106 N.m/rad. Finalmente, uma convenção standard de robôs é proposta e cuja finalidade é corrigir os erros previamente identificados através de um algoritmo de compensação global e independente do fabricante do robô considerado.
