Characteristics of Self-Synchronization of Dual-Rotors System

Abstract:

The characteristics of the self-synchronization in the offset self-synchronous system are put forward. In the paper, based on Lagrange principle, a dynamic model is derived to give its electromechanical-coupling model, which is provided with many variable no-linear characters. A serious of the practical phenomena in the transition process of the system is reasonably explained using the numerical solution simulation, and the variations rules of each parameter in the system are discussed at several types of the typical status. Finally the characteristics of the self-synchronization in the system are generated under the action of the electromechanical coupling. The visually processes are shown in the simulation results, for which the conventional mechanic models are unavailable to explain quantitatively, in which the vibration machines implement fully the transition from asynchronous to synchronous state or from one type of synchronous state to other type. It is fully verified that the system is with the self-healing synchronous ability, and the synchronous movement rules in the electromechanical coupling system are also revealed. For its research not only it is useful to explore the electromechanical coupling model of the offset self-synchronous system, but also it is in-depth to study synchronous motion rules of the self-synchronous system, and it is of the theoretical and practical importance.
