Resumen
The predictive philosophy contributes to improving productivity, reducing system
failures and reducing unplanned downtime in a non-invasive way to the machine, for which the
test bench is based on the German standard VDI2221, using mathematical models to select the
materials and the design of the final prototype. The development of the project consists of
applying vibration analysis, thermographic analysis and the quality of energy in which each
measurement and the correlation that exist between them is shown; in addition, the inverse
Fourier transform was used to demonstrate the amplitude and frequency ranges according to the
theoretical equation proposed in the Matlab program, it can also be seen the higher order
vibrations of 22.1 is located at the same critical point of the SP7 measurement with a temperature
of 34.6 ° C and an emissivity of 0.95, likewise the Power quality measurements are within the
allowable limits according to ISO 50001; On the other hand, this analysis made it possible to
determine the existence of a positive linear correlation between thermography and vibration
analyzes with a correlation coefficient equal to 0.828.
