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 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 elastic restraint; change the period of forced periodic migration of the end of elastic restraint and adjust resonance oscillations of the set amplitude; thereat forced periodic migration to the end of elastic restraint is imparted by 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 described way is realised by means of the corresponding device.
EFFECT: provision of excitation of resonance mechanical oscillations without application of the equilibrating mass or the base at automatic maintenance of a preset value of controllable parameter of resonance oscillations in case of technological change of the sloshing mass.
