DOUBLE-FREQUENCY RESONANCE VIBRATION TABLE

摘要

A double-frequency resonance vibration table contains a three-mass mechanical vibrating system, in which a working body is connected by elastic elements to reactive and active masses, and a core with armatures of electromagnetic vibration exciters. The working body is installed on a fixed basis through shock absorbers, and the core with armatures of electromagnetic vibration exciters are installed on the working body and reactive mass respectively.
