Longitudinal oscillations in the innessity of the ideal liquid, in the hard ring cylindrical tank with else basis.

Abstract

Frequency equation of proper longitudinal (axisymmetric) oscillations of ideal incompressible liquid in weightlessness, which is located in a rigid ring cylindrical reservoir with elastic bases in the form of thin circular plates, is written out and analyzed. Unknown coefficients of the frequency equation for the various limiting cases of degeneration of ring plates in circular, in membranes, in absolutely rigid plates are calculated. The influence of weightlessness and mechanical parameters on the frequency spectrum is estimated.
