Frequency modal analysis of liquid/gas interaction in cylindrical container covered by thin circular plate
Horáček, Jaromír ; Gorman, D. G. ; Griffond-Boitier, F.
The aim is to determine frequency-modal characteristics of the coupled system and to show when the fluid-structural and/or liquid-gas couplings are important for the dynamic behavior of the structure or fluid. A general theoretical solution is derived and the analytical-numerical results are partially compared with results obtained by finite element method (FEM) using ANSYS program code.
Dynamická analýza tenkostěnné kruhové desky ovlivněné interakcí s kapalně-plynným prostředím v elastické válcové kavitě
Horáček, Jaromír ; Griffond-Boitier, F.
The study deals with the free vibration analysis of a cylindrical thick-walled cavity filled by a gas axially bounded at one end by a liquid interface and by a thin elastic disc at the other end. Numerical calculations performed are compared with theoretical solution and with the experimental results. The interaction between water and air in a rigid cavity was also studied. The influence of a compliance of the rigid cavity on the natural frequencies was taken into account for comparison with experimental data.
