A dual-frequency resonant vibration system comprises a working body, a reaction mass, a core of armature of electromagnetic exciters installed on the working body and reaction mass respectively, and stops. The working body is mounted on a fixed base through vibration isolators and is rigidly connected to the elastic elements of different hardness. The stops are based by free ends on the elastic elements, and between the stops the reactive mass is freely installed. |
