combined motion

The problem of motion of the cylindrical reservoir, partially filled with liquid, on pendulum suspension is considered in combined statement.  The system motion occurs under the presence of uniform outflowing of liquid with the neglect of outflowing local effects.  It was shown that the constructed mathematical model of the system describes the main mechanical effects and does not violate the conservation laws.  Peculiarities the system dynamics under the presence of liquid outflowing are shown by the numerical examples of the system behavior for initial kinematic perturbation and under the

Dynamical behavior of liquid in a reservoir of revolution under vibration disturbance of reservoir motion is studied within the framework of the model of combined motion. We focus main attention on the system behavior in below resonant range. For analysis of peculiarities of the system behavior we compare the development of wave generation for cylindrical, conic, spherical, hyperboloid (one-sheet and two-sheet) reservoirs.

Variation of resonant properties of the system liquid – structure caused by changes of distribution of normal frequencies is under consideration. It was shown that different types of mobility of carrying body (translational or rotational motion with different types of constraints) causes growth of normal frequencies, which correspond to antisymmetric oscillations of a liquid free surface, while the rest of frequencies do not change.  General arrangement of normal frequencies, which corresponds to the case of immovable reservoir, is considerably violated.
