Delo obravnava problematiko neuravnoteženja togih rotorjev ter izdelavo merilnega sistema z grafičnim uporabniškim vmesnikom za identifikacijo debalansa. V prvem delu je predstavljeno teoretično ozadje problema in pomen balansiranja, v nadaljevanju pa izdelava in uporaba sistema za identifikacijo. Merilni sistem je izdelan iz komponent proizvajalca Beckhoff, signale pa se v realnem času spremlja in zajema s pomočjo programskega okolja TwinCAT. Za upravljanje je izdelan grafični uporabniški vmesnik v programskem jeziku Python. Za namen komunikacije med Python-om in TwinCAT-om je uporabljena knjižnica pyads. Delo je zaradi najboljše kompatibilnosti z merilnim sistemom potekalo na industrijskem računalniku Beckhoff. Izdelan merilni sistem s pomočjo grafičnega uporabniškega vmesnika omogoča merjenje in shranjevanje signalov iz naprave za dinamično balansiranje togega rotorja, ki so potrebni za določitev njegove masne neuravnoteženosti.

• Title: Development of a measurement system with the graphic user interface for the identification of rigid rotor unbalance

Abstract

This work deals with the problem of unbalance of rigid rotors and development of measurement system with graphic user interface for the identification of rigid rotor unbalance. The first part presents the theoretical background and the importance of mass balancing followed by development and use of measurement system. The measurement system is assembled from Beckhoff’s components and the signals are monitored and acquired in real time with TwinCAT software environment. For user control a graphic user interface in Python programming language is developed. Pyads library is used to allow Python to interact with TwinCAT. Due to the best compatibility the work is done on Beckhoff industrial computer. The developed measurement system allows measuring and storing signals from the rigid rotor dynamic balancing device, which are needed to determine rotor’s mass unbalance.
