| Abstract |
The movement of an elastic panel is considered in an ideal liquid flow. It is assumed that the
panel vibrates with small amplitude and is subject to external mechanical effects to resist these vibrations. The problem of optimizing the vibration damping process is formulated followed by solving
through estimation using the quadratic energy criterion. The necessary optimum conditions are
derived and applied to suppress hydroelastic vibrations within a finite time interval. An iteration vibration damping algorithm is presented based on sequential solution of direct problems of interaction
between the moving liquid and the panel. The algorithm also involves solving adjoint problems of
inverse integration of a homogeneous equation consisting of sequential determination of the corre-
sponding approximation to obtain the optimum control to suppress vibrations. The algorithm proposed to optimize vibration damping is illustrated by an example of determining the stabilizing effect
in analytical form. |
