Harmonic Vibration Control Synchronization Simulation for Double Exciting Motors of Single-Mass Nonlinear System

Abstract

For nonlinear harmonic vibration synchronization vibration machine have been widely used in metallurgy, mining, agriculture and other fields, but the harmonic vibration synchronization mechanism for the multi-excitation sources which used to driven the nonlinear vibration machine to realize the harmonic vibration synchronization movement is not clear. In order to study the problem, the nonlinear electromechanical coupling dynamic model has been established for the single-mass harmonic vibration synchronization nonlinear machine in the paper, and by analyzing the coupling dynamic characteristics of the double exciting motors, the harmonic vibration control synchronous simulation model and corresponding harmonic vibration control synchronization strategy have been established. Under the different initial conditions and different Working conditions, the harmonic vibration control synchronization process for the double exciting motors have been simulated. Based on the simulation results, the harmonic vibration control synchronization mechanism for the double exciting motors which used to drive the nonlinear vibration machine have been analyzed and discussed, and the validity of the harmonic vibration control synchronization strategy for the double exciting motors to realize the harmonic vibration synchronization movement has been verified. All these can provide the reference basis for the subsequent nonlinear vibration machine to carry out the harmonic vibration synchronization status application.Introduction
