FIELD: technological processes.
SUBSTANCE: invention is referred to the vibration equipment and can be used in various branches of economic activities. The way of excitation and maintenance of resonance mechanical oscillations lies in the following: resonance oscillations of mass on elastic restraint are excited by forced periodic migration of the opposite end of the elastic restraint; change the period of forced periodic migration of the end of elastic restraint; thereat, forced periodic migration to the end of elastic restraint is imparted by a driving force of the inertia created by the electromagnetic vibrator, the electromagnetic vibrator is kept in space of vibration-isolating elastic restraint with a foundation. The specified method is realised by the corresponding device.
EFFECT: provision of excitation of resonance mechanical oscillations without application of the equilibrating mass or the base at manual smooth regulation of controllable parameter of resonance oscillations of mass.
