Implementación de un sistema de control y monitoreo mediante un servidor web local para un actuador electromecánico portable para ensayos a flexión de materiales compuestos de matriz polimérica según ASTM D 7264

Abstract

The objective of this study is to establish the advantages and benefits of the implementation of a control and monitoring system directed from a local web server for the bending testing machine of polymeric matrix composite materials. By implementing a communication system that uses an IP address in a local network programmed in LOGO! Web Editor was able to establish a remote control that allows the results to be processed, viewed, and downloaded to external devices. In addition, in the innovation process, an analog output module was added to modify the speed applied in the tests. These actions were able to improve the scope of the team, allowing it to carry out 2 types of new tests that favor the determination of mechanical properties of composite materials. The first performs tests at different speeds with the same load, the second is aimed at determining the cycles that the mass supports, the speed of movement of the rod of the hydraulic cylinder varies during the test. The changes made to the machine significantly benefit users, it was finally established that when testing acrylic specimens under the ASTM D7264 standard at the same load, material failure occurs at a higher speed. It is recommended to implement a uniaxial type of mechanical strain gauge that allows measuring the axial deformations that a material may present after the bending test is carried out, in addition, the need to implement a new speed module is established to allow increasing the current speed with which it is carried out the tests.
