Transverse vibration analysis of a prestressed thin circular plate in contact with an acoustic cavity
Result description
This paper describes the free transverse vibration analysis of a thin circular plate, subjected to in plane stretching, whilst in interaction with a cylindrical acoustic cavity. An analysis is performed which combines the equations describing the plate and the acoustic cavity to form a matrix equation which, when solved, produces the natural frequencies of the coupled system and associated vectors. The results are compared with computations using FE code ANSYS.

Analýza příčných kmitů předepjaté kruhové desky v kontaktu s akustickou dutinou
Czech description
Článek se zabývá příčnými volnými kmity tenké kruhové desky staticky předepnuté ve střední rovině, která kmitá v interakci s válcovou akustickou dutinou. Analytické řešení vázaných rovnic pro kmitání desky a vzduchu v kavitě je dovedeno do formy maticovérovnice pro vlastní frekvence a tvary kmitu vázaného systému. Výsledky jsou porovnány s výpočty MKP pomocí programu ANSYS.
