Abstract
Los medios de transporte son un punto clave del desarrollo de los países y de la interconexión de las poblaciones, por lo que la mejora continua de los mismos supone una obligación a la par que un reto.
El medio de transporte seleccionado para su mejora es el monorraíl, en el que un solo carril sirve como vía para el transporte de carga o pasajeros. En la mayoría de los casos el monorraíl circula en suspensión, pero también puede hacerlo a nivel del suelo o por túneles. Es, por tanto, un medio de transporte que ofrece múltiples posibilidades, por el propio concepto y por tratarse de un medio de transporte eficiente, limpio y seguro.
En el presente Trabajo Fin de Máster se recoge el desarrollo del diseño de una propuesta de optimización del sistema de tracción y fijación de los sistemas de monorraíl existentes así como la viabilidad técnica de la misma.
En el primer capítulo del documento se realiza un análisis de los sistemas de monorraíl existentes, desde los monorraíles que circulan en suspensión hasta los monorraíles que circulan sobre una vía, incluyendo los magnéticos.
Una vez analizados los principales sistemas de monorraíl se ha llevado a cabo un análisis técnico comparativo de dichos sistemas para la cuantificación de los mismos, evaluando los puntos fuertes y débiles de cada uno para compilar lo mejor de cada uno en el diseño conceptual del sistema a desarrollar.
Definida la idea del sistema a desarrollar, se detallan los parámetros básicos del sistema y las características del mismo a lo largo del Capítulo 4, incluyendo los elementos comerciales seleccionados para satisfacer las especificaciones propuestas.
En los capítulos 5 y 6 se modela y optimiza el sistema de tracción-fijación del modelo, sometiéndolo a distintas situaciones de carga límites para analizar posteriormente los resultados obtenidos.
Con el modelo optimizado y definido, se describe un posible proceso de fabricación y montaje así como las principales tareas de mantenimiento a realizar.
En los últimos capítulos se realiza el modelado en AutoCAD y se obtienen los planos del modelo desarrollado a lo largo del Trabajo.
The means of transportation are a key point in the development of countries and the population interconnection, so the continuous improvement of them involves an obligation and a challenge as well. The means of transport selected for improvement is the monorail, which serves as a single rail track to transport cargo or passengers. In most cases the monorail drives around suspension, but can drive at ground level or tunnels. It is therefore a means of transport that offers multiple possibilities, because of the concept itself and because it is an efficient, safe and clean transportation mean. In this Master's Thesis is collected the development of the design of an optimization proposal of the existing traction and fixing systems of the monorail as well as the technical feasibility. In the first chapter of the document an analysis of existing monorail system is carried out from the suspended, not suspended and magnetic monorails. After analyzing the main monorail system it has been carried out a comparative technical analysis of such systems to quantify them, assessing the strengths and weaknesses of each point to compile the best of each one in the conceptual design of the system to be developed. Once defined the system idea to develop, the basic parameters of the system and its characteristics are detailed throughout the Chapter 4, including commercial elements selected to meet the specifications proposed. In chapters 5 and 6 the traction-fixing system model are modeled and optimized, subjecting it to various loading limited conditions and then analyzing the results. With the optimized and defined model, a possible process of manufacture and assembly is described as well as major maintenance work to be performed. In the last chapters the modeling is done by AutoCAD, and the planes of the model are obtained throughout the Master´s Thesis development.
