Abstract
La presencia de fisuras en los ejes de cualquier tipo de maquinaria es un grave problema para la integridad de los mismos. Con el avance de las tecnologías se han desarrollados máquinas cuyos ejes giran a altísimas velocidades, aumentando aún más los riesgos relacionados con la posible aparición de fisuras. Por ello, es importante poder anticiparse a la fractura de un eje, sustituyéndolo cuando se aprecien evidencias de que está fisurado. En este estudio se trata de crear una herramienta informática que sea capaz de determinar la órbita que describe el centro de un eje fisurado y sometido a cargas externas. Mediante el análisis de estas órbitas se podrá comprender mejor cómo se comportan los ejes en estas circunstancias, y en el futuro, desarrollar sistemas que sean capaces de detectar fisuras analizando exclusivamente la órbita que describe el eje. ______________________________________________________________________________________________________________________________________
The presence of cracks is a serious problem for the integrity of the shafts of any type of machinery. The progress of technologies has enabled the development of machines whose shafts rotate at high speeds, further increasing the risks associated with the possible appearance of cracks. When an evidence of a crack is noticed it is important to anticipate the failure of the shaft, by replacing it. This study seeks to create an IT tool able to determine the orbit described by the center of a cracked shaft under external loads. Analyzing these orbits it will be better understood how shafts behave under those circumstances, and in the future, to develop systems capable of detecting cracks by analyzing the orbit described by the shaft.
