Analiza barvnih interferogramov statičnih kontaktov : zaključna naloga Univerzitetnega študijskega programa I. stopnje Strojništvo - Razvojno raziskovalni programKusterle, Blaž, strojnikDa bi omogočili prenos energije in majhno trenje pri medsebojnem gibanju različnih komponent v dinamskih mehanskih sistemih, so ti sestavljeni iz kontaktov. Tam zaradi majhnih kontaktnih površin ... prihaja do visokih tlakov, zato jih je potrebno mazati. Večina kontaktov deluje v ElastoHidroDinamičnemu (EHD) režimu mazanja. Za merjenje debeline mazalnega filma obstaja več metod, v našem zaključnem delu pa bomo uporabili barvno optično interferometrijo, ki temelji na modelnem stiku med jekleno kroglico in stekleno ploščo. Uporabili smo RGB barvni prostor. Naš cilj je bil napisati programsko kodo, ki izračuna debelino mazalnega filma za poljuben barvni interferogram. Najprej smo obravnavali interferograme generirane s svetlobo z neomejeno koherenco, nato z omejeno koherenco, zatem pa smo valovanju z omejeno koherenco dodali še šum detektorja, da se čimbolj približamo realnim interferogramom. S pomočjo dvožarkovne interference smo pri obremenitvi statičnega kontakta z 20 N generirali barvne interferograme kontakta za vse tri primere. Z interferogramom, kjer upoštevamo, da je koherenca valovanja omejena in ima dodan šum, smo izdelali kalibracijsko krivuljo. Z njo smo za barvni interferogram, generiran z neznano obremenitvijo izračunali debelino reže izven kontakta in s pomočjo debeline določili, s kakšno obremenitvijo je bil kontakt generiran.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [B.
