【摘要】 同步现象广泛存在于工程领域中,双偏心回转式激振器驱动的同步振动系统可以简化为一个双转子自同步系统。以某典型万能同步实验台为对象,定量研究几种典型情况时该自同步振动系统各参数变化的规律及其同步特征,结果充分验证了该类振动系统具有自行恢复同步的能力。以该实验台实测数据为参考,与实测结果进行对比,证明了仿真计算结果的合理性。并且,通过实验和仿真发现激振力不等情况下,即使关掉激振力大的电动机电源,系统仍能自行恢复振动同步状态。更多还原

【Abstract】 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.更多还原
