A nivel térmico el modelo considera de forma transitoria en el tiempo los fenómenos de generación de calor por fricción y transferencia de calor sobre las barras que intervienen en el proceso. Adicionalmente, se acopló un modelo mecánico que permite estudiar el comportamiento plástico de la junta al actualizar en el tiempo el esfuerzo de fluencia del material acorde con la evolución del perfil de temperaturas. Además, el modelo mecánico enriquece el modelo de generación de calor y permite considerar el calor generado por deformación. Para validar el modelo construido se simularon tres condiciones de proceso diferentes y se compararon con resultados experimentales reportados en la literatura. Los procesos de validación corresponden a una condición de RFWDD símil de baja deformación, RFWDD símil de alta deformación y RFWDD disímil entre cobre y hierro. (Texto tomado de la fuente)This research describes and evaluates a numerical model developed for the simulation of the thermomechanical behavior present during the Rotary Friction Welding process operate in Direct-Drive (RFWDD). At a thermal level, the model considers the phenomena of heat generation by friction and heat transfer on the bars that involved in the process in a transitory way over time. Additionally, a mechanical model was used to study the plastic behavior of the joint by updating the yield stress of the material over time according to the evolution of the temperature profile Furthermore, the mechanical model enriches the heat generation model and allows considering the heat generated by deformation. To validate the built model, three different process conditions were simulated and compared with experimental results reported in the literature. The validation processes correspond to a condition of RFWDD-similar low strain, RFWDD-similar high strain and RFWDD-dissimilar between copper and iron.MaestríaMagister en Ingeniería MecánicaLa metodología llevada a cabo fue la siguiente: primero se realizó una identificación de los fenómenos físicos que intervienen en el proceso de soldadura, luego se plantearon las respectivas ecuaciones que gobiernan el comportamiento termomecánico de las piezas a soldar. Posteriormente, se construyó un modelo FEM termomecánico acoplado que permitió describir y relacionar los fenómenos de generación de calor, transferencia de calor y deformación plástica. Este modelo se validó de forma secuencial empezando por una simulación símil de baja deformación donde se evaluaron diferentes estrategias para describir el comportamiento del esfuerzo de fluencia a diferentes temperaturas. Luego se validó el modelo con un caso símil de alta deformación. Posteriormente se realizó un análisis paramétrico que relacionó las variables de proceso de velocidad angular y presión axial, con las características macroscópicas de la junta. Finalmente se validó el modelo con un caso disímil de alta deformación entre cobre y hierro a diferentes condiciones de presión de fricción.Modelado matemático de sistemasxiv, 120 páginasapplication/pdfspaUniversidad Nacional de ColombiaBogotá - Ingeniería - Maestría en Ingeniería - Ingeniería MecánicaFacultad de IngenieríaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá510 - Matemáticas::519 - Probabilidades y matemáticas aplicadas670 - Manufactura::671 - Proceso de metalurgia y productos metálicos primariosMETODO DE ELEMENTOS FINITOSSOLDADURAFinite element methodWeldingSoldadura por fricción rotacionalFricciónDeformación plásticaElementos finitosRotational friction weldingFrictionPlastic deformationFinite elementsConstrucción de un modelo de elementos finitos para el estudio del comportamiento termomecánico de una junta durante el proceso de soldadura por Fricción Rotativa de Control Directo (RFWDD)Construction of a finite element model to study the thermomechanical behavior of a joint during the Rotary Friction Welding process by Direct Drive (RFWDD)Trabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionTexthttp://purl.org/redcol/resource_type/TMInternational Energy Agency, “World Energy Outlook 2013,” National Energy Information Center, 2013.Grupo de las Naciones Unidas para el Desarrollo (UNDG), Desafíos y estrategias para el Desarrollo Sostenible en América Latina y el Caribe. 2018.ONU, “Objetivos de desarrollo sustentable,” ExpoKnews, 2015.
