Dynamics of reservoirs of revolution partly filled with a liquid that are caused by a complex impulse load

Abstract

The problem of translational motion of the mechanical system “reservoir of revolution – liquid with a free surface“ under rectangular impulse of force applied to reservoir wall is under investigation. We compare reservoir motion under impulse loading in the case of considering and neglecting of liquid mobility effect. Differences in system motion caused by wavy motion of liquid were shown, which mainly result in manifestation of undesired oscillations of the reservoir. We consider variant of elimination of these phenomenon by means of insertion of additional control into the system, namely, compensation of main vector of forces of liquid pressure on reservoir walls. Efficiency of these technique is shown by the examples.
