| Summary: | The method of laser vibrometry was applied to investigate the vibrations of elastic plates interacting with a liquid for different variants of plate clamping. The obtained results are used to verify the developed finite-element algorithm designed to solve the problem of spatial vibrations of one or two parallel rectangular plates interacting with a quiescent viscous fluid. The results of calculations of the natural frequencies and damping decrement obtained under different boundary conditions and the height of the fluid layer are discussed. It has been demonstrated that for the configurations considered, viscosity of the liquid has a significant effect on the damping decrement, in contrast to frequencies of vibrations. |
