Desarrollo de una aplicación informática para adquisición y análisis de señales de vibraciones de modos de falla mecánicos

Abstract

This thesis designed and implemented a modular development of vibration analysis laboratory practice; the modular consists of a software application and simulators of failure modes. The informatics application “VISUALspectrum” has been designed using the software (LabVIEW) Laboratory Virtual Instrument Engineering Workbrench, containing the most relevant characteristics of a vibrations Analyzer, with a very friendly interface for the user inspired by the MAINtraq Viewer software. To determine the characteristics of “VISUALspectrum” the content of the given subject in class was studied about vibration analysis, resulting in the need of an application which delivers wave forms and spectrums of the magnitude of displacement, speed and acceleration as well as of the surrounding. Simulators of failure modes have been designed and built for practices with particular attention to material selection and the quality of machining, in order to avoid making manufacturing mistakes that develop vibrations signs of failure modes that must not exist. For each lab practice has been prepared both its respective guide, and VISUALspectrum application user’s manual. After performing a statistical comparison between the measurements of vibrations VIBRACHECK 200 ABG analyzer and the application VISUALspectrum, resulted in lower variation coefficients, validating to the VISUALspectrum application as an a effective tool for the analysis of vibration and additionally of lower cost for the Faculty of Mechanics.
