Analysis of the Coupling Action in Nonlinear Harmonic Vibration Synchronization System

Abstract

The nonlinear harmonic vibration system that synchronously excited by two eccentric rotors is a kind of typical synchronous vibration machine which possesses the typical coupled motion characteristics. Because of the nonlinear vibration motion of the vibrating body, which make the two eccentric rotors to reach the coupling synchronous rotary motion, and the coupling action will result in the change of the motion characteristics and movement patterns for the two eccentric rotors, eventually to achieve the coupling synchronous motion. Based on the nonlinear vibration theory, the paper has established the electromechanical coupling nonlinear dynamics equations of the nonlinear harmonic vibration system. By analyzing the coupling factor of the two eccentric rotors, the influence to the equilibrium state of the nonlinear vibration system because of the nonlinear coupling strength has been discussed, and the synchronous movement evolution procedure of the two eccentric rotors has been researched further. Based on the research result, the engineering method that to design the structural parameters of the nonlinear harmonic synchronization vibration machine which excited by two eccentric rotors has been deduced in the paper also.KeywordsNonlinear systemHarmonic vibrationTwo-eccentric rotorsCoupling action
