自同步振动和振动同步传动在机械工程上已获得成功应用 ,但是振动机械实现自同步振动和振动同步传动的过渡过程长期以来却一直不明确 ,利用现有的振动机械模型还不能定量解释系统从不同步到同步、或是从一种同步状态过渡到另一种同步状态的物理过程。本文对此进行了专门的研究 ,在传统的振动机械模型基础上建立了电机 -振动机械系统的机电耦合模型 ,利用该模型进行数值模拟对过渡过程中的一系列实际现象做出了合理的定量解释 ,揭示了自同步振动和振动同步传动的机电耦合机理 Self-synchronizing vibration and vibration synchronous transmission have been successfully applied in mechanical engineering. However, the transition process of self-synchronous vibration and synchronous vibration transmission has not been clearly established for a long time now. It is still impossible to quantitatively explain the system from the existing vibration mechanical model Not synchronized to the synchronization, or from a synchronized state transition to another physical state of the synchronization process. In this paper, a special study has been carried out. Based on the traditional vibration mechanical model, the electromechanical coupling model of the motor-vibration mechanical system is established. Using this model to conduct numerical simulation, a series of practical phenomena in the transition process are rationally quantified Explain and reveal the electromechanical coupling mechanism of self-synchronous vibration and vibration synchronous transmission
