Diseño y desarrollo de un instrumento y método para medir la frecuencia natural de una banda mediante el sensor mpu-6050 y Arduino para el laboratorio de diagnóstico técnico de la Facultad de Mecánica de la ESPOCH

Abstract

This project was carried out to develop an instrument that can measure natural frequencies in bands of pulley transmission systems. This study used an MPU6050 sensor, a touch screen, a rechargeable battery, and an Arduino board. The development of the method and the measurement programming was based on the SKF Frequency Meter algorithm to measure natural frequencies in belts, which consists of entering the values of the diameters of the largest and smallest pulleys, the distance between centers, the density of the belt, and the application of a light blow on the belt to obtain the value of the natural frequency of the bands. By using a Fourier Transform library in Arduino programming, the natural frequencies sensed by the MPU6050 sensor were determined. The results in the readings of the developed instrument showed erroneous measurements compared to the SKF Frequency Meter; however, to calibrate the device, 30 readings were taken with each piece of equipment (developed tool and SKF Frequency Meter), and the calculation of a correction factor. With the readings, the margin of error was reduced to 0.05 Hertz units of the instrument, obtaining measurements similar to the SKF equipment.
