Influence of the acoustic-structural couplings upon free vibrations of mechanical systems
The roles of acoustic-structural couplings in three entirely different aeroelastic systems are compared. The first system is a thin elastic cylindrical shell containing fluid in a coaxial annular duct, the second system is a thin plate vibrating in fluid near a rigid wall, and the third system is a simple single degree-of-freedom mechanical system, vibrating in contact with a confined volume of an acoustic medium. It is shown that the nature of the acous-tic-structural coupling is identical in all the studied cases.
