Texte intégralLa Tesis está organizada de tal manera que sea fácil su seguimiento. Por esta razón, los capítulos se han escrito siguiendo una secuencia lógica. Una breve descripción de los capítulos se presenta a continuación.
El primer capítulo trata de los aspectos generales del Control Estructural con un especial énfasis en los disipadores de fricción, los cuales se incluyen en el llamado enfoque de 'Control Pasivo'.
El Capítulo 2 proporciona un repaso general al estado del conocimiento relativo a los principios de la fricción seca y a la investigación y aplicación de los dispositivos disipadores de fricción, así como a sus simulaciones numéricas.
Un procedimiento numérico ha sido desarrollado (programa ALMA) en los Capítulos 3 (edificios de una sola planta) y 4 (edificios de varias plantas) para llevar a cabo simulaciones numéricas de edificios equipados con disipadores de fricción y los resultados obtenidos fueron comparados a los que se obtuvieron con el programa comercial ADINA. La similitud entre los resultados de ambos programas es aceptable.
El Capítulo 5 describe los ensayos sobre una mesa vibratoria que se hicieron en dos modelos de edificios: uno de una sola planta y otro de dos plantas; ambos equipados con disipadores de fricción. Los resultados obtenidos se compararon a los resultados conseguidos con ALMA. Los resultados coinciden aceptablemente.
Luego de probar la validez del programa ALMA, éste se usó para hacer un estudio numérico preliminar para obtener la llamada 'carga óptima de deslizamiento' de los disipadores de fricción en el Capítulo 5. Las curvas que se pueden dibujar a partir de los resultados obtenidos con este estudio, pueden ser aplicadas para determinar las cargas óptimas de deslizamiento de edificios de una y varias plantas.
Finalmente, el Capítulo 7 contiene las conclusiones de esta Tesis y algunas propuestas para las futuras líneas de investigación.
Además, se han incluido cinco apéndices. El Apéndice A contiene los principios básicos del Análisis del Contacto. El Apéndice B trata de la solución numérica de las ecuaciones de movimiento para sistemas de uno y varios grados de libertada. Este apéndice está muy relacionado con el contenido de los Capítulos 3 y 4 de esta Tesis. El Apéndice C describe la solución de las ecuaciones de movimiento usando multiplicadores de Lagrange. El Apéndice D describe el equipo de laboratorio y la instrumentación usada en los ensayos. Los resultados de éstos, y la comparación entre éstos y los resultados numéricos (programa ALMA), son presentados en el Apéndice E.

Texte intégralNowadays, centrifugal fans are widely used in many industrial applications such as automotive, aeronautic, vacuum cleaner, etc. Due to their high adaptability, they can operate over a wide flow range especially with high speed rotation. In order to reduce the impact on environment, centrifugal fan as other energy conversion system has to display a high efficiency. However, a better understanding of their working and of the rotor-stator interaction is required to enhance their design and to make them widely integrated in current applications. The purpose of this study is to analyze and to quantify the influence of the solidity vaned diffusers on the performance of a centrifugal fan. A computational study has been conducted to analyze the performance of a centrifugal fan under various levels of impeller-diffuser interactions. The objective was to understand the pressure recovery phenomena in each diffuser. Different geometries were proposed to reduce both separation flow phenomenon and viscous losses. The geometries are all composed with the same impeller and return channel, only the vaned diffusers differ; the trailing edges are maintained at the same position while the leading edges have different radial positions. The characterization of the fan has been realized by an experimental setup designed and built in agreement to the standards ISO 5801 and 516

Texte intégralIn this dissertation are presented the main theorical concepts involved in the action of the jets formed in ski jump spillways on stilling basins type pre-excavated scour hole, from the path of the jet in its air stage and in his submerged phase, with particular emphasis on hydrodynamic pressures and its characterization by the bottom of the basin. To experimentally study the action of the jets in stilling basins, was used a physical model in scale 1:100 built in Hydraulic Works Laboratory of IPH/UFRGS with experiments of different flow rates and different depths of pre-excavated scour hole. The data were extracted from experiments on the physical model through extensive instrumentation, using gates, piezometers, pressure sensors, images and other equipment. A careful analysis of the data generated in the physical model from the jet images in your path through the air was performed and the flow of the jet in its submerged phase, comparing the model data to the results obtained by traditional methods of calculation. The pressure data generated during the tests and presented the results for the mean pressures and dynamic pressures were also analyzed. Dynamic pressures observed in the physical model were compared with those calculated by means of theoretical methods for the purpose of evaluating the quality of this methodology for use in engineering projects, where we observed large differences in magnitude of pressure when in shallow water beds, and diferences in pressure distribution over the stilling basin bottom, especially when in deep water beds. In order to adjust the applied methodology, it was proposed to change parameters governing the shape of the pressure bulb and the application of a pressure damping coefficient, and thus was possible to significantly improved the distribution and magnitude of the calculated pressures due to action of the jets in the stilling basin bottom. The results have been satisfactory up to a certain distance after the peak pressure caused by the jet, and after this point the hydraulic jump effects prevail and should be investigated in future studies.

Texte intégralEn la present tesi, dos BVR totalment metàl·lics s’han dissenyat, fabricat i assajat, satisfent tots dos els requeriments dels protocols definits per les normes europees i americanes. Estan formats per un element de travat ranurat que estabilitza el nucli metàl·lic. El primer d’ells, el Braç de Vinclament Restringit Modular (BVRM), està format per diversos mòduls seriats que a la vegada contenen diverses unitats de dissipació, que plastifiquen sota esforços tallants, connectades en paral·lel. Tot i que té un bon comportament histerètic i una gran ductilitat, el nucli és pesat i difícil de fabricar. El segon braç, anomenat Braç de Vinclament Restringit Ranurat (BVRR), soluciona aquests inconvenients. Plastifica sota esforços axials, de la mateixa manera que els BVR convencionals, però el nucli massís és substituït per una platina perforada. Aquest nucli consisteix en un únic element composat per dos bandes laterals, dissenyades per a plastificar i amb una secció quasi constant, connectades per diversos ponts estabilitzadors que es mantenen sempre en el seu rang elàstic. Aquests ponts, juntament amb l’element de travat, impedeixen el vinclament de les bandes laterals. S’han proposat diverses expressions de disseny pels dos braços. S’ha formulat i implementat, en un programa d’elements finits comercial, un model de material per a simular numèricament el comportament dels braços, reduint així la dependència dels assajos a escala real durant el seu procés de disseny

According to the related research about the scouring effects of free over-fall will be used in this study. The situation will be discussed in steady flow by using different energy dissipators — apron, water cushion and secondary dam. Facilities, the protected effect and the comparative characteristics of scouring hole will be found (such as the max. depth, max. length, shape factor and volume) in downstream of the energy dissipators. The result would be determined by energy dissipating theory, which is the relations between the scale of dissipators and energy variation. In view of energy disspators, the water cushion had the result of protection better than apron, because of the current hits mutually at the water pond. And the height factorβ=0.13 is the best. The situation of the secondary dam is the moving bed, therefore analysis of the scouring characteristic to make use energy variety of system. In both the rigid and soft energy disspators, the energy loss of scouring increased with slop. The degree of scouring depth and volume could be lowered effectively in rigid energy disspators. In water cushion, the average decreased rate of the scouring length about is 40 percent, and the scouring volume quantity decreases rate reaches 40 percent at least. Although, scouring length can’t be decreased at apron disspators. The scour phenomenon be mollified to a downstream region for protective effects. Scouring is more serious between major and secondary dam if the distance is too short from both of them. Character factorα>1.56 is the suggested application. In this experiment condition, a simple formula is proposed for a relevant establishment. It is expected to be helpful in designs of energy disspators.
