The present work is a lucubration and verification of the previous research through theory and experiment. Because of the physical model of the published paper is oversimplified, the revised model is proposed in present research. And the small parameter averaging method and Routh-Hurwitz criterion are adopted to investigate the stability criterion and synchronization condition. Numerical analyses are given to discuss the relation between synchronous characteristics and structural parameters of the vibrating system. And then some simulations are given to research the synchronous mechanism of the system. Besides, an experimental platform is set up to test the dynamic characteristics and synchronization, which verifies the correctness of theoretical analysis and numerical simulations. The theory, numerical simulation and experiment demonstrate that the synchronous state of two identical rotors mounted symmetrically is independent on the variation of installation positions of two exciters. Finally, the error of the experiment datum is analyzed. This study will provide theoretical reference for the design of secondary isolation vibration screen.

本工作是通过理论和实验对前人研究的深入和验证。由于已发表论文的物理模型过于简化，本研究提出了修正模型。并采用小参数平均法和Routh-Hurwitz准则研究稳定性准则和同步条件。数值分析讨论了振动系统的同步特性与结构参数之间的关系。然后通过仿真研究了系统的同步机制。此外，还搭建了实验平台，对动力学特性和同步性进行了测试，验证了理论分析和数值模拟的正确性。理论，数值模拟和实验表明，对称安装的两个相同转子的同步状态与两个励磁机安装位置的变化无关。最后对实验数据的误差进行了分析。本研究将为二次隔振筛的设计提供理论参考。
