Implementación de un módulo de simulación para el diagnóstico vibracional de la desalineación de ejes para el rotor kit del laboratorio de diagnóstico técnico y eficiencia energética

Abstract

This curricular integration work had as objective to implement a simulation module for the study of the vibrational analysis of shaft misalignment for the rotor kit of the Technical Diagnostic and Energy Efficiency Laboratory at ESPOCH. It started with the review of the theoretical information to know the types of misalignment that occur in the shafts and the characteristic spectral appearance of the shafts. Afterwards, the corresponding calculations were made for the selection of the mechanical parts, then the elements were modeled with their respective dimensioning using the Solidworks Academic software, which were taken as a reference at the time of its construction. For the data collection, the module was aligned with the Laser Aligner equipment with the purpose of having a starting point to begin the misalignment, then the shaft was misaligned at 0,15mm intervals starting from 0,00mm being the starting point until reaching 0,75mm. Through the Vibracheck ABG 200 equipment the data and the vibration spectra characteristic of the misalignment were obtained by placing the accelerometer in the inserts in the module horizontal, vertical and axial. An analysis with the data obtained was carried out using tables and graphs to understand how the harmonics characteristic of the misalignment are presented. Then, an alert value of 3,566mm/s was calculated to determine the level of displacement where the displacement starts to generate failures in the module components. It is concluded that the rear of the electric motor is the best point for misalignment analysis because the data obtained has a higher linear relationship. It is recommended to perform more displacement levels to better demonstrate the misalignment behavior.
