摘　　要：建立了反向回转双机驱动振动系统的动力学模型,通过动力学分析,根据振动系统的动力学模型和感应电机的数学模型进行了计算机仿真,结果表明其自同步状态较差。然后分析了基于两个偏心块相位差对双机驱动振动系统进行控制的方法,对振动系统进行优化设计,计算机仿真结果表明该系统实现了速度同步和相位同步,验证了优化设计的有效性。The dynamic model of vibration system driven by dual-motor in reverse direction was established. Through dynamic analysis of the vibration system, the simulation based on the dynamic model of vibration system and the mathematics model of induction motor was made. Simulation results show that the system is in a poor synchronous state. The method to control phase difference of the two eccentric rotors was analyzed, and the vibration system was optimized. Computer simulation demonstrates that the vibration system realizes speed synchronization and phase synchronization. The results verify the effectiveness of the optimal design.
