摘要：
The dimensionless coupling equations of two unbalanced rotors (DCEOTUR) in a dual-mass planar motion vibrating system are derived by virtue of the averaging method with modified small parameters. The synchronization and stability criteria are developed through investigating the existence and stability of the zero solution of DCEOTUR. The synchronization ability coefficient and the loading coefficient are defined. By numeric analysis, the effect of the dynamic parameters on the characteristics of the coupling dynamics of the two unbalanced rotors is discussed to determine the dynamic parameter intervals of stable synchronization. The results demonstrate that the stable phase difference of synchronization maybe corresponds to the minimum or maximum one of the loading coefficient of the system with variation of the system dynamic parameters. Due to the coupling effect of the dual masses, the synchronization torque drives the phase difference of the two unbalanced rotors close to the minimum point of the loading coefficient in the certain intervals of dynamic parameters, while in other intervals, it drives the phase difference close to the maximum point of the loading coefficient. Computer simulations verify the above results. © 2016, Nanjing Univ. of Aeronautics an Astronautics. All right reserved.
