Aiming at the problem that the same frequency excitation vibration system is not conducive to screening diverse materials and the vibration system with different frequency cannot realize synchronous motion with arbitrary constant speed ratio， a constant speed ratio controlled synchronization method of double excitation vibration system is proposed. The dynamic equation of the vibration system driven by two reverse rotating machines is established by using Lagrange equation， and the response equations of the constant speed ratio of the vibration system are deduced. The fuzzy proportional-integral-derivative （PID） controlled method is designed by using Matlab/Simulink， and the constant speed ratio controller is designed based on the master-slave control mode， so that the two excitation reverse drive constant speed ratio vibration system can control the synchronous motion. The constant speed ratio parameters selected in this paper are 1.2 and 1.5， respectively. The simulation results show that the vibration synchronization of vibration system cannot achieve the given constant speed ratio， but the controlled synchronization can be achieved. The effectiveness of constant speed ratio controlled by synchronization theory for two excitation driven vibration system is verified by experiments.
