We consider vibration devices that consist of softly vibration-isolated rigid bodies subjected to vibrations transmitted by means inertial exciters (unbalanced rotors) driven into rotation electric motors. Typically, when designing such devices, it is assumed the rotors rotate uniformly with a certain circular frequency and body performs small harmonic oscillations same frequency. The present w...

Abstract We examine and analyze vibrational resonance (VR) in a dual-frequency-driven gyroscope subject to parametric excitation an additive periodic forces. The method of direct separation the fast slow motions is used derive response amplitude analytically from equation for oscillations system, terms parameters high-frequency signal excitation. Numerical simulations are carried out validate t...
