Interakcija turbulentnega toka s konzolno podprto tanko ploščo

Čufar, Krištof (author), Prezelj, Jurij (mentor)

Zaključno delo se ukvarja z aerodinamičnim vzbujanjem konzolno vpete tanke plošče ter razlikovanjem med vibracijsko in aerodinamično generiranim hrupom. Izveden je bil eksperiment, v katerem smo s počasnim zračnim curkom vzbujali konzolno vpeto tanko ploščo, ter opazovali odziv njenih vibracij v odvisnosti od frekvence. Razloženi so posamezni vplivi na vibracijski odziv tanke plošče.

• Title: Interaction of turbulent flow with simply supported thin plate

Abstract

The thesis deals with an aerodynamicly excited simply supported thin plate and the distinction between vibration generated and aerodynamicly generated noise. An experiment was carried out in which we used a slow air jet to excite a cantilever-mounted thin plate and observed the response of its vibrations as a function of frequency. The individual effects on the vibration response of a thin plate are explained.
