Akustične lastnosti ukulel : diplomsko delo = Acoustic properties of ukuleles : B. Sc. thesisŠunta, GregorV nalogi smo izdelali računalniški model že izdelane kupljene ukulele, in naredili eksperimentalno modalno analizo. V Solidwoksu smo izdelali model inštrumenta na podlagi izmerjenih dimenzij ... sestavljene ukulele. Narejeni model smo prenesli v Ansys, kjer smo s pomočjo metode končnih elementov naredili modalno analizo inštrumenta. Ker nismo poznali mehanskih lastnosti lesa, iz katerega je bila ukulela izdelana, smo modelu določili začetne lastnosti. Hkrati smo na ukuleli naredili eksperimentalno modalno analizo, kjer smo izmerili lastne frekvence zgornje in spodnje plošče. V nadaljevanju smo prilagajali mehanske lastnosti materiala računalniškega modela, dokler nismo dosegli zadovoljivega ujemanja izračunanih lastnih frekvenc z izmerjenimi. Iz narejenega modela smo ugotovili, da lahko kljub nenatančnemu poznavanju mehanskih lastnosti lesa, iz katerega je ukulela izdelana, naredimo njen model z ustrezno natančnostjo.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [G.
