Abstract
Neuravnoteženo togo telo, ki se vrti okoli svoje osi, povzroča sile in vibracije v podporah. Vibracije lahko močno poškodujejo strukturo naprave in vplivajo na njeno življensko dobo. Merjenje vibracij nam omogoča karakterizacijo debalansa neuravnotežnih rotorjev. Diplomsko delo tako zajema teoretično in eksperimentalno analizo vibracij neuravnoteženega rotorja. V okviru naloge je bila izdelana improvizirana naprava za merjenje debalansa rotorjev. Programiranje naprave je potekalo v programskem okolju Arduino Software (IDE). Meritve so bile opravljene s pomočjo MEMS pospeškomerov, ki smo jih namestili na podpore gredi. Balansiranje smo uspešno opravili na testnem rotorju.

Title:Characterization of rotor imbalance using MEMS accelerometers
Abstract:
An unbalanced rigid body that rotates around its axis, causes forces and vibrations in supports. Vibrations can severely damage the structure of the device and affect its lifetime. The measurement of vibration signal allows us to characterize the imbalance of the unbalanced rotor. The work presents the theoretical and experimental analysis of the vibrations of an unbalanced rotor. For the measuring purposes, we presented the device for measuring the imbalance of the rotors. Program was written in the Arduino Software (IDE). The measurements were made using MEMS accelerometers, which were installed on the supports of the shaft. The balancing procedure was successfully performed on the test rotor.
