PHENOMENA IN STANDING WAVE IMPACT ON A HORIZONTAL PLATE

Abstract

The paper deals with experimental and theoretical investigations of dynamics of a plate-fluid system. In experiments, a horizontal plate was suspended elastically in a wave flume and loaded with impact pressure forces resulting from growing water waves. The data obtained in experiments has revealed the essential role of the elasticity of the plate and its supports as well as the fluid compressibility in estimating the structure-fluid interactions. Therefore, in order to get a better insight into the problem considered, harmonic vibrations of an elastic bandplate submerged in an infinite domain of compressible fluid have also been examined. The solution obtained and formulae derived enable to calculate the fluid pressure induced by the plate vibrations.
