摘　　要：自同步振动和振动同步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到另一种同步状态的物理过程。本文根据振动系统的机电耦合数学模型,建立了基于Matlab/Simulink的仿真模型。通过对几种典型自同步振动过渡过程的机电耦合行为的仿真分析,揭示了多电机激振振动系统自同步振动和振动同步的机电耦合机理,验证了建立的机电耦合模型的正确性,为进一步开发新型高效的振动筛提供了理论基础。Although self-synchronous vibration and vibratory synchronization transmission have been applied in mechanical engineering successfully, the＇transient processes of self-synchronization and synchronization transmission in vibratory machines are still obscure. The physical processes of vibratory machines from asynchronous condition to synchronous condition or from one type of synchronous condition to another could not be explained quantitatively according to available mechanical models. In this paper, according to the electromechanical-coupling mathematical model, its simulation model is built by Matlab/Simulink. After running the simulation model under several transitional processes, the electromechanical-coupling mechanism of self-synchronous vibration and the vibratory synchronization transmission of the vibrating system with two-motor-driving are showed, and validate the correctness of the simulation model. Provide the theoretical fundamental for the further exploitation of economical and efficient new style shaker.
