| Description
| - In vibration monitoring of a structure it is usually assumed the absence of an interaction and any fluid effects which can cause changes in natural frequency. In certain cases, this cannot be assumed and it is necessary to extract values of natural frequencies of the structure with no interaction from the values for the structure with fluid interaction from the values measured. This paper considers a thin circular plate in contact with a fluid cavity giving rise to strong structural/fluid vibration interaction. The paper details the free vibration analysis of the coupled system and through consideration of modal energy, illustrates how the affined modes of vibration of the plate and the fluid can be qualitatively described. The paper then introduces a method by which the natural frequencies of the plate in the absence of interaction can be obtained from those of the plate in interaction with the fluid.

- Při monitorování vibrací nějaké konstrukce se obvykle předpokládá absence interakce a jakékoli fluidní účinky, které mohou zapřičinit změny vlastních frekvencí. V určitých případech toto není možno předpokládat a je nutné extrahovat vlastní frekvence konstrukce bez interakce z hodnot pro konstrukci v interakci s tekutinou, z naměřených hodnot. Článek uvažuje tenkostěnou kruhovou desku v kontaktu s fluidní kavitou přičemž vzniká silná strukturně - fluidní vibrační interakce. Článek se zabývá detailní analýzou volných kmitů vázaného systému a pomocí úvah o modální energie je ilustrováno jak mohou být kvalitativně popsány afinní tvary kmitání desky a tekutiny. Pak je uvedena metoda, kterou lze získat vlastní frekvence desky bez interakce z hodnot pro desku v interakci s tekutinou. (cs)
