Abstract
U ovom radu analizirane su vibracije cilindričnih posuda koje sadrže tekućinu. Iznijete su teorije slobodnih i prisilnih vibracija posude sa sadržanom tekućinom. Razmatrani su faktori koji utječu na vibracije posude, posebice utjecaj razine sadržane tekućine. Predstavljena je Reissnerova teorija plitkih stijenki, na kojoj je temeljen aproksimativni analitički proračun vlastitih frekvencija posude sa sadržanom tekućinom. Modalna analiza posude sa sadržanom tekućinom provedena je metodom konačnih elemenata u softveru Ansys, te su dobiveni rezultati uspoređeni s onima iz referentne literature. Analiza prigušenih prisilnih vibracija provedena je također metodom konačnih elemenata u softveru Ansys analizom odziva na harmonijsku pobudu s obzirom na ranije određene modalne karakteristike posude sa sadržanom tekućinom. Vrijednosti prigušenih odziva određene su na rezonantnim frekvencijama. Promatran je utjecaj razine tekućine u posudi na intenzitet prigušenog odziva posude unutar frekvencijskog intervala interesa.
Abstract (english)
In this paper vibrations of cylindrical vessels containing liquid are analyzed. Free and forced vibrations theories of vessels containing liquid are presented. Vessel vibrations participating factors are observed, especially level of contained liquid. Reissner shallow shell theory is presented, on which approximate calculation of vessel's containing liquid eigenfrequencies is based. Modal analysis of vessel containing liquid is conducted using finite element method software Ansys, analysis results are compared to those from referent literature. Analysis of damped forced vibrations is also conducted using finite element method software Ansys Harmonic response analysis, considering modal characteristics of vessel containing liquid determined earlier. Damped response values are determined on resonant frequencies. Effect of contained liquid level on vessel response intensity within frequency range of interest is observed.
