Diseño de una máquina digital de ensayos a impacto tipo Charpy, para la caracterización de materiales compuestos con matriz polimérica.

Abstract

The charpy pendulum impact testers are machines used in the testing of various materials from metals to polymers and composites, in order to identify the mechanical properties to impact that these have, this device consists as its name suggests of a pendulum that rises to a previously established height and then is allowed to fall freely and then impact a standardized specimen of the material to test. This project develops the design and automation of a charpy impact machine focused mainly on composite materials with polymeric matrix. This design is carried out taking into account the development process of a mechatronic product, first the concept of the equipment is developed taking into account the ASTM 6110 standard and implementing the five-step method proposed by Ulrich and Eppinger, obtaining an approximate description of the technology, principles of operation and shape of the product, after this, through a theoretical analysis and with the help of software a 3D model is made which is simulated and tested by the finite element method using the software for computer aided engineering ANSYS. Once the optimal dimensions of the machine are obtained, we proceed to the selection of the automation parts with their respective programming and assembly in the 3D model.
