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

Abstract

The objective of this project was the building of a resonance simulation module that could allow students to analyze the resonance phenomenon, using a mass-spring system as foundation to represent the simplest machine to recognize the concepts of frequency, mass, and stiffness. The first step was defining the parameters of the operation, establishing the natural frequency to the machine in 26 Hz and knowing the magnitude of the mass, it was possible to calculate the stiffness of the system. Once these parameters were defined the next step was to design a 3D model using SolidWorks academic software; and based on the previous calculations results was established to have four springs to withstand the module. Therefore, the bases, anchorage elements, union elements and the motor, were organized to the suitable physical space. With the module designed, the building of the elements was done considering materials that were suitable to produce the resonance phenomenon without deforming its physical properties in a long term, but at the same time to be affordable; therefore, the A36 and A277 steels were chosen to build the bases and springs respectively, and nylon for the auxiliary elements. The module was ready for the testing, using the MAINTraq Viewer software and the Vibracheck analyzer. The gathering of the data was done varying the frequency of the motor’s rotation as it reached the critical speed of the system in the spectrum. Once the tests have carried out, it is concluded that the module correctly simulates the resonance phenomenon under the stablished design parameters. It is recommended to check the correct fixing of the modules in the workbenches to avoid the appearance of other harmonics that could mistake the reading of the results.
