FIELD: technological processes.
SUBSTANCE: invention is referred to the vibration equipment and can be used in various branches of economic activities. The method of excitation of resonance mechanical oscillations lies in the following: resonance oscillations of mass on elastic restraint excite by forced periodic migration of the opposite end of elastic restraint, change the period of forced periodic migration of the end of elastic restraint and adjust resonance oscillations of set amplitude. Thereat, forced periodic migration to the end of elastic restraint is imparted by the slugged vibrator, the slugged vibrator is kept in space using vibration-isolating elastic restraint with a foundation, resonance oscillations are excited in area of the period of oscillations To which is selected under the formula 
thus withstand parity C>>Co, where Co - rigidity vibration-isolating elastic restraint. The device for excitation of resonance mechanical oscillations contains the mass connected to an elastic element which opposite end is joined to the mechanism of forced periodic migration, the mechanism is executed with possibility of change of the period of forced periodic migration, and the slugged vibrator with the control block is used as the mechanism of forced periodic migration, connected to a foundation through a vibration-isolating elastic suspension, the elastic element is executed with the rigidity, determined under the formula 
the vibration-isolating elastic suspension is executed with rigidity Co linked with rigidity of an elastic element by parity Co<<C.
EFFECT: provision of excitation of resonance mechanical oscillations without application of the equilibrating mass or the base.
