Abstract：The conditions of self-synchronization and motion stability regarding a dual-motor drive vibrating mechanism with a two-stage vibration isolation frame are studied. Owing to the effect of the two-stage vibration isolation, this mechanism enables not only enough oscillation amplitude of the material box to screen the material but also reduces the dynamic load transmitted to the foundation. This paper begins with utilizing Lagrange equation to establish differential motion equations of the vibrating mechanism, and follows with a modified average small parameter method to obtain the dimensionless coupled equation of the eccentric rotors. Then the condition of existence for zero solution of dimensionless coupled equation of the eccentric rotors is used to achieve the condition to implement self-synchronous motion of the vibrating mechanism, and the stability condition of self-synchronous motion is obtained by the Routh-Hurwitz criterion. Finally, the numerical simulations are carried out to verify the correctness of the theoretical analysis.
