Investigation of the effect of self-resonance of vibration excitation systems

摘要

Eccentric type dis-balance type vibration excitation systems are analysed in the paper. It is assumed that the dis-balance has an additional degree of freedom. 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 driving shaft's angular frequency is high, but the generated vibration frequency is relatively low . Experimental investigations of the effect of self-resonance enabled to define the zones of existence of such motion modes. Such principle of vibration excitation can be successfully exploited in different areas of engineering as it eliminated the necessity of complex and expensive vibration control and stabilisation equipment.
