Diseño de una máquina para pre-crecimiento de grietas por fatiga en probetas de ensayo de tenacidad a fractura. Solución hidráulica

Abstract

F racture toughness tests on aluminum specimens are routinely conducted in the laboratories of the Mechanical Engineering Department at the Engineering School, University of Seville. High flow rate and high capacity comercial servo-hydraulic testing rigs are used to this end. Needless to say, the operation of this testing machines is expensive and the Department has been looking for ways to reduced the expenses incurred. An idea that has been put forward, and which is explored in this project, is to employ a simpler and more basic machine for the first part of the test, the pre-cracking stage, where the requirements in terms of load capacity and precision in the controller can be dramatically reduced.

En la Escuela Técnica Superior de Ingeniería de Sevilla se realizan unos ensayos de tenacidad a fractura a unas probetas de aluminio gracias a unas máquinas impulsadas por un circuito oleohidráulico. Este ensayo puede dividirse en dos etapas: una primera en la que la grieta precrece, y una segunda en la que se ensaya la probeta hasta que esta se rompe. El objetivo de este trabajo es diseñar una nueva máquina hidráulica que realice la primera parte de estos ensayos para reducir la carga de trabajo de las máquinas existentes.
