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

Abstract

This curricular integration work consisted on implementing a simulation module for the vibrational diagnosis of the unbalance for the rotor kit of the Technical Diagnosis and Energy Efficiency laboratory. The respective analysis of the design and modulation in the SolidWorks Academic software. The construction of the test bank that conformed the rotor kit was developed, for the construction of the most relevant element which is the unbalance disk. Nylon was used because it is lighter, since it helped the unbalance to be more noticeable at full speed. In this way it was possible to simulate and verify the most evident failures that can occur in an industry caused by the vibration generated by the unbalance, with the help of the vibration analyzer Vibracheck ABG 200 and two accelerometers the data of speed and displacement in the different planes were collected: vertical, horizontal and axial that make up the module. For the respective interpretation of results, the MAINTraq: Predictive, Viewer and Analyzer softwares was used, where the different spectra and waveforms that characterize each type of unbalance in the 1X harmonic were identified. The measurements were performed at different rotation frequencies and varying the mass from 21.40 to 31.40 grams; with the velocity data obtained, the respective analysis and interpretation of graphs of all the velocity amplitudes generated in the mentioned planes was performed. In conclusion, it could be observed how the amplitude of the velocity spectrum increases with a value that starts at 4,59 to 9,97 mm/s as the mass increases. It is recommended to take the measurements in the vertical plane of the supports so that their respective velocity vectors and phase angles determine the behavior of the different types of unbalance.
