Abstract: Using the equivalent linearization method, the compensation and influence of the main vibration spring stiffness to the movement stability of the nonlinear resonance machine which synchronously driven by double exciting motors have been discussed. And using the singular perturbation theory, the influence of the nonlinear force which caused by load fluctuate to the stability of the vibration machine have been researched also. By the experiment and the actual production application, the validity of the mechanical motion stability analysis conclusion for the double motors synchronously exciting nonlinear vibration machine has been verified. The research conclusions that carried out in the paper have important reference value for the dynamic analysis and practical debugging of the double motors synchronously exciting nonlinear vibration machine.


Keywords: Dynamics, Stability, Nonlinear vibration, Synchronization, Acceleration sensor.
