Abstract
En el presente proyecto se tratará la modelización y análisis de dos diseños de cuadros de bicicleta. En concreto, los cuadros a diseñar y analizar son cuadros para bicicleta de montaña rígidos.
Para llevar a cabo el proyecto se utilizarán herramientas de modelado y simulación cada vez más presentes en la ingeniería, y que facilitan el estudio del producto antes de la realización del prototipo consiguiendo disminuir el tiempo de fabricación y abaratando costes.
En cuanto a la elaboración del proyecto se tratará de conocer, en primer lugar, la evolución de los cuadros hasta la actualidad, las modalidades de ciclismo de montaña que existen y las características de los cuadros utilizados en cada una, los materiales utilizados en la fabricación de los cuadros, y, por último, las técnicas de fabricación. Una vez recopilada dicha información, se utilizará para desarrollar los diseños y realizar los análisis correspondientes.
En segundo lugar, se estudiarán los parámetros geométricos que influyen en el diseño del cuadro y se detallarán las características requeridas de los modelos. Los cuadros a realizar son un cuadro que simula la fabricación mediante tubos soldados y otro que simula una configuración monocasco, es decir, fabricado en una única pieza.
Por último, una vez realizados los diseños, se procederá a aplicar la normativa vigente para ensayarlos. Esto se realizará con el fin de comparar los modelos entre sí y con otros similares.
This project will deal with the modeling and analysis of two designs of bicycle frames, using the well-known, finite element method. Particularly, the frames to be designed and analyzed are made for hardtail mountain bicycles. To carry out the project will be used modeling and simulation tools that are widely used in engineering nowadays, and that make easier the study of the product before the manufacturing of the prototype, reducing time and costs of prototyping process. In order to prepare the project, it will be necessary to know, first of all, the evolution of the bicycle frames up to the present time, the different modalities of mountain biking that are practiced and the characteristics of the frames used in each one of them. It is also important to study which materials are used in the manufacturing process of the frames, and the techniques used on them. Once this information has been collected, it will be put into practice to develop the designs and perform the proper analyzes. Secondly, we will study the geometric parameters applied in the bicycles frames and will be detailed the characteristics required for them. One of the frames will be designed by simulating that it has been made with welded pipes, and the other model simulates a monocoque configuration, that is, made in a single piece. Finally, once the designs have been made, we will apply the current regulations to test both frames. The aim of these tests is to compare both frames with each other and with similar models that bicycles brands show on their product catalogues.
