The self-resonance effect of the planetary vibration excitation systems

Planetary type vibration excitation systems are analyzed in the paper. It is shown that resonance vibrations in such systems can occur in the regime of self-resonance, which is understood as a mode of motion when the angular frequency of a driving shaft is high, but the generated vibration frequency is relatively low. Theoretical investigations of the effect of selfresonance enabled to define the conditions of existence and stability of such motion modes in planetary vibroexciter. Such principle of vibration excitation can be successfully exploited in different areas of engineering as it eliminates the necessity of complex and expensive vibration control and stabilization equipment.
