Abstract:

The hydroelastic oscillation problem of a three-layer plate, forming slit channel wall of supporting device is investigated. The three-layer elastic plate is clamped at its butt ends. The plate oscillations are caused by pulsation of viscous incompressible liquid in the slit channel. We investigate the flat problem for the regime of stationary harmonic oscillations. As a result, the mathematical model of supporting device was built and we have proposed the approaches for its study.

Keywords: hydroelasticity, oscillations, three-layer plate, pressure pulsation, viscous incompressible liquid
