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.

Comparative analysis of the results of natural frequencies and bending vibrations determination for the metal mast lifting device with the application of theoretical and experimental methods is conducted in this article. In particular, results of the mathematical modeling of the transverse vibrations of the mast with the application of S. s theory and matrix method of initial parameters are considered, as well as the results of the experimental research of mast vibrations of a real lifting device.

The description of law frequency vibrocavitator design for cavitational processing of chemically active liquids, liquids under pressure and high temperature is carried out. Its basic design and technological parameters are set up; by controlling them one can choose optimal regimes of cavitational processing. A special device for choosing range frequency fluctuation of cavitation breakers is developed.
