摘要/Abstract

摘要： 提出了一种双质体三机驱动自同步振动系统。推导出了双质体振动系统的运动微分方程,并给出了系统的机电耦合数学模型。建立了新的机电耦合仿真模型。最后,运用控制变量法以数值试验的方式研究了中间弹簧刚度、共振、激振力以及电机安装位置对系统自同步性以及同步相位差角的影响。研究结果表明：双质体振动系统在一定条件下能实现稳定的同步运动;中间弹簧刚度、激振力以及电机安装位置对系统的同步特性均有较大的影响;系统处于共振状态时,不能实现同步;上质体两电机水平安装距离的增大,有利于系统同步运动的实现。

Abstract: A double mass vibrating system of self-synchronization with tri-exciter was put forward. The dynamic differential equation of the double mass vibrating system was established and the electromechanical coupling mathematical model was got. The new electromechanical coupling simulation model was built. By the method of controlling variables, the effects of various factors, such as stiffness of middle spring, resonance, centrifugal force and motor mounting position on self-synchronization of the system and phase difference were studied in a numerical experiment manner. The research results show this system can achieve a stably synchronized motion under certain conditions. The stiffness of intermediate spring, exciting force and installation position of motors have a significant impact on the performance of the system synchronization. System synchronization can’t be obtained when the resonance happens. Increasing horizontal mounting distance of motors of upper body benefits system synchronization.

Key words: double mass vibrating system, electromechanical coupling, controlling variables, self- synchronization
