Self-synchronous vibrating system which was driven by two rotating exciters and moved in a 2-D space can be simplified as a self-synchronization system with dual-rotors. A typical omnipotent vibrating synchronization experiment machine was used as a prototype, variation rule of each parameter and synchronous characteristics about self-synchronization vibrating system at several representative state were quantificationally discussed and validated owning self-synchronization ability. Base on measured data of omnipotent vibrating synchronization experiment machine, the synchronous characteristics of the system were compared with measured data. Its rationality was testified. Besides, base on the measured data and emulational result, the system was found to own the self-synchronization ability for the uneven vibration force in self-synchronization vibrating system at the measure and emulation mode, even though the power supply of motion with big vibration force was shut off.
