Identifikacija napak elektronsko komutiranih puhal na podlagi meritev zvočnega tlaka in pospeška : magistrsko delo magistrskega študijskega programa II. stopnje StrojništvoČemažar, GašperV tem delu so predstavljene najpogostejše napake v proizvodnem procesu elektronsko komutiranega industrijskega puhala. Predstavimo tudi elementarne vire hrupa in vibracij puhala. Osredotočimo se na ... mehanski vir hrupa, ki nastane kot posledica strukturnih vibracij ležajev. Opišemo tudi metode za odkrivanje napak na ležajih. Za identifikacijo napak na ležajih uporabimo Hilbertovo transformacijo signala zvočnega tlaka in pospeškov vibracij, s katero dobimo ovojnico signala. Princip delovanja analize ovojnice najprej preverimo s sintetičnim eksperimentom simulirane napake na ležaju. Z analizo ovojnice smo uspešno identificirali tipične frekvence poškodovanih ležajev puhala tako na podlagi pospeškov kot tudi zvočnega tlaka.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [G.
