Abstract
En este proyecto se va a tratar el estudio de una tabla de snowboard mediante el uso de un código comercial de elementos finitos. A ésta se le introducirán unas piezas de un material no newtoniano alojadas en el núcleo de madera, situadas a ambos lados de cada fijación. El objetivo de dichas piezas es retrasar la rotura de la tabla disipando la energía acumulada en la intersección fijación-tabla como consecuencia de un fuerte impacto contra un obstáculo, o bien proporcionar una mejora en la flexión de la tabla en cualquiera de los trucos comúnmente realizados sobre una barandilla en un snowpark.
En el software utilizado se han realizado cuatro modelos, dos modelos con la estructura de una tabla convencional la cual será sometida a un ensayo de impacto y a un ensayo de flexión, y otros dos modelos en los cuales se han incluido piezas de material no newtoniano insertadas en el núcleo, y que se han sometido a los mismos ensayos que la tabla convencional.
El resultado es la comparación de ambos modelos con ambos ensayos donde se podrá comprobar la funcionalidad de este material no newtoniano en el interior de una tabla de snowboard.
This project focuses on the study of a snowboard using a commercial finite element code. Some pieces of non-Newtonian material are placed inside the wood core, located on both sides of each fixing. The aim of such pieces is to delay the breaking of the board, dissipating the energy stored in the intersection "fixation-board" due to a strong impact against an obstacle, or provide improved bending to the board in any of the tricks commonly performed on a railing on a snowpark. Four models have been built in the software used, two of them with a conventional structure of a board which will be subjected to an impact test and a bending test, and two other models in which non-Newtonian pieces has been inserted within the core, subjected to the same kind of tests as the conventional board. The result is the comparison between both models and both tests, where the functionality of the non-Newtonian material inside a snowboard will be checked.
