Vibro-akustična karakterizacija sestavljenih struktur : doktorsko delo

Pirnat, Miha, strojnik

Raziskava predstavi vibro-akustično karakterizacijo sistema komora-plošča, ki je geometrijsko in fizikalno analogen energetskemu transformatorju. Najprej je predstavljen in validiran pristop k ... modeliranju lastne dinamike lamelirane strukture, ki v primeru energetskega transformatorja predstavlja enega izmed glavnih izvorov hrupa. Za primer danega notranjega akustičnega vzbujanja je razvit vibro-akustični model sistema komora-plošča, ki omogoča določitev akustičnega in strukturnega odziva sistema, ter temelji na zaporedni uporabi pristopa modalnega sklapljanja in metode robnih elementov. Razviti vibro-akustični model je tudi uspešno eksperimentalno validiran na namensko izdelanem preizkuševališču. Z uporabo validiranega modela so v zadnjem delu raziskave analizirane nekatere modifikacije sistema komora-plošča z namenom izboljšanja njegovih vibro-akustičnih lastnosti.
