Širokospektralne vibracijske obremenitve prožnih struktur : diplomska naloga univerzitetnega študijaMršnik, MatjažDelo obravnava vibracijsko utrujanje, natančneje, določanje števila obremenitvenih ciklov in njihovih amplitud skozi življenjsko dobo tehnične komponente. K temu se pristopi v časovni domeni, v ... časovni zgodovini obremenitve in v frekvenčni domeni, na podlagi močnostnega spektra obremenitve. Popisana je obravnava obremenitve kot naključnega procesa in način preračuna življenjske dobe z metodami v frekvenčni domeni. Pripravljen je računalniški program za numerični preračun ocene življenjske dobe na podlagi podane obremenitve. Podani sta skupina generiranih in skupina izmerjenih obremenitev, za katere se določi življenjska doba z različnimi metodami vrednotenja utrujanja. Ocene življenjske dobe v frekvenčni domeni so primerjane z oceno v časovni domeni. Ena izmed metod, razvil jo je Dirlik, se izkaže za zelo zanesljivo in tako omogoča statistično obravnavo obremenitve ter zmanjšano numerično zahtevnost vrednotenja utrujanja na poljubni konstrukciji.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
