Abstract
Este documento trata sobre el estudio tensional de los anclajes (seguros) utilizados en la escalada deportiva. Debido a la importancia de estos elementos se intentará conocer su comportamiento al producirse una caída y establecer qué parámetros deberían ser modificados para mejorar su vida útil. Se partirá de la fuerza de rozamiento en el freno, que es el elemento que detiene la caída, como primer parámetro de estudio. Será necesario comparar y analizar el comportamiento de los anclajes al producirse una caída, siendo detenida por un freno estático primero y posteriormente por uno dinámico. Para ello en este proyecto se modela con Solid Edge tres tipos diferentes de anclaje y se suponen tres posiciones distintas que se establecerán al simular la caída. Dicha simulación se realizará mediante un método de elementos finitos, siendo ANSYS en su entorno Workbench el elegido. Por último se realiza una comparación entre los diagramas de tensiones obtenidos para cada anclaje y orientación, con el fin de averiguar en que circunstancia y bajo qué parámetros los anclajes se comportan de mejor manera. _______________________________________________________________________________________________________________
This document deals with the stress study of the anchors (protection) used in professional climbing. Due to the importance of these elements we will try to predict their behaviour when a fall occurs and establish which parameters should be modified to improve their useful life. The frictional force on the brake, which is the element that stops the fall, will be used as the first studied parameter . It will be necessary to compare and analyze the behaviour of anchors when a fall occurs, being stopped by a static brake first and then by a dynamic brake. It is necessary in this work to model three different anchor types positioned in three different ways to simulate a fall. This simulation will be developed by using the Finite Element Method, with ANSYS Workbench. Finally, a comparison between the stress diagrams obtained for each anchor and orientation, is carried out to find what circumstances the anchors parameters work better.
