Prototype of small-scale test machine for vibration measurement on bearings

Repetitive movements of shaft in bearings over time intervals generate vibrations. The aim of this research is to build the prototype of small scale of machine to measure the vibration values of bearing due to spinning shaft using an accelerometer and Arduino sensor device. The method used is to build a device of miniature rotating machines which was used to simulate machine vibrations. The ADXL345 accelerometer measured the magnitudes of vibration that occurs on the rotating shaft. Arduino Uno analyzed data from ADXL345. The amplitude, speed, acceleration and frequency values were measured according to rotation values. It was found the largest amplitude, speed, acceleration and frequency values were obtained at the radial point Y1 position.
