FIELD: electrical engineering.
SUBSTANCE: present invention relates to vibration engineering. The proposed device has an electromagnet, an electromagnet armature and additional loads. The electromagnet is rigidly fixed to the stator part of the vibrator. The electromagnet armature and additional loads are rigidly fixed to the plate of the armature part of the vibrator. The stator and armature parts are joined to each other by an elastic system. The elastic system consists of helical springs, clamped in pairs using tension bolts between the stator part of the vibrator and the support plate. The tension bolts are fitted outside these springs and are rigidly fixed to the stator part of the vibrator. The plate of the stator part of the vibrator is clamped between springs with possibility of oscillating along the axes of the springs without separation from their ends. The vibrator is made with possibility of rigid attachment to the working component of a vibration machine and vibration effect on the working component in resonance oscillation mode. The electromagnet is in form of a solenoid and is put inside the helical coiled springs. The electromagnet armature is in form of a long rod and enters the electromagnet at a certain distance, which is determined experimentally.
EFFECT: increased amplitude of relative oscillations of the armature and stator parts, simple design of the device.
