Abstract
El principal objetivo de este proyecto es calcular y analizar el fallo de un eje
ferroviario a través de la simulación por elementos finitos en Abaqus. En concreto, se
diseñará un eje ferroviario y se le someterá a diferentes cargas hasta conseguir el fallo del
material y estudiar el inicio y propagación de la grieta.
Para llevar a cabo el proyecto:
Se recopilará documentación sobre ejes ferroviarios, mecánica de la fractura y
sobre el uso del programa informático ABAQUS.
Se realizará un pequeño manual sobre el programa informático debido a la poca
existencia de dicho material.
Se implementará el diseño del eje en un modelo 3D, desarrollado sobre el programa
informático ABAQUS.
Se simulará el fallo del material mediante la aplicación de elementos finitos
ABAQUS.
Se analizará y estudiará el resultado obtenido.
The main objective of this project is to calculate and analyze the failure of a rail link through the finite element simulation in Abaqus. Specifically, a rail link will be designed and subjected different loads until the failure of the material and study the propagation of the crack. To carry out the project: Railways documentation, fracture mechanics and the use of ABAQUS software was collected. A small manual on the software due to the low presence of such material is made. The shaft design a 3D model developed on ABAQUS software was implemented. The failure of the material will be simulated by applying ABAQUS finite element. It will analyze and study the result.
