METHOD OF EXCITING VIBRATIONS Russian patent published in 2013 - IPC B06B1/16 

FIELD: process engineering.

SUBSTANCE: invention relates to vibratory technology and may be used in vibrating machines in mining, construction, and other industries. Proposed invention comprises engaging solid of revolution with counter body by calibration force to roll it over the latter at frequency lower than that of excited vibrations. Note here that said solid of revolution is rolled along unclosed path that features rotary symmetry about axis of symmetry of said path. Note also that oscillation frequency is controlled by relationship while amplitude is controlled by formula where P_ax is axial calibration force of engagement between solid of revolution and counter body; ω_rot is frequency of rotation of the solid of revolution; m is weight of solid of revolution; 1 is radius of solid of revolution; j is stiffness of the rod of solid of revolution; D is diameter of solid of revolution in area of its engagement with counter body.

EFFECT: higher efficiency.
