摘要： 以反向回转激励的振动系统为对象,建立了考虑驱动电机机械特性的动力学方程.通过数值仿真计算,研究了激振器的偏心矩、电机功率、偏心转子回转摩擦阻矩等参数对自同步运动的影响.结果表明,激振器各参数在一定阈值内可以实现系统稳定同步运动,振动体y方向振幅与偏心矩成正比,实现稳定同步的时间与偏心矩成反比.电机额定转矩对系统同步影响不明显,而回转阻尼系数主要影响同步的过渡过程时间.

Abstract: The dynamic equations of a self-synchronous vibration system driven by two exciters rotating oppositely are deduced taking account of the mechanical characteristics of the two driving motors. By numerical simulation, the effects of the exciters' eccentric torque, motor power and resisting moment due to rotating friction on self-synchronization motion are discussed. The results show that the vibration system can achieve stably synchronous motion if all the exciter parameters are within certain threshold values. The amplitude of vibrating body in y direction is in direct proportion to eccentric torque, thus realizing that the time for stable synchronization is in inverse proportion to eccentric torque. The effect of the rated torque of motor on synchronization is not obvious, while the rotary damping parameter mainly affects the time required to transfer to synchronization.
