Masno uravnoteženje togega rotorja preko meritev sil na ležajih : zaključna naloga Razvojno raziskovalnega programa I. stopnje Strojništvo

Fratnik Kobe, Jan

V zaključni nalogi je obravnavan problem masnega neuravnoteženja togega rotorja pri vrtenju okoli stalne osi, zaradi katerega se na ležajnih mestih pojavijo dinamične sile, ki povzročajo vibracije in ... hrup. V prvem delu smo v programskem jeziku Python pripravili programsko kodo, ki zajet signal iz silomerov filtrira, nato pa na podlagi poznanih sil v ležajih omogoča odpravo oz. zmanjšanje neuravnoteženosti rotorja. Signal je bilo potrebno najprej filtrirati zaradi šuma, za kar smo uporabili Butterworthov tip filtra iz knjižnice SciPy. V nadaljevanju smo realni rotor s pomočjo izdelanega programa uravnotežili, nato pa smo z uporabo dodatnih mas namerno povzročili neuravnoteženost in jo poskušali v nekaj iteracijah odpraviti. V nalogi je prikazano, da lahko z ustreznimi postopki odvzemanja ali dodajanja materiala znatno zmanjšamo sile pri vrtenju togega telesa.
