Dynamic research of double swing vibration exciter based on bond and linear graphs

介绍了双摆激振装置的工作原理,并组建了简化的物理模型。随后,引入了线图和键图分析方法,并针对双摆激振装置的物理模型分别构建了线图模型和键图模型,通过求解对应的方程组,可获得关于激振源、摆1、摆2角速度的状态方程,通过状态方程,可以直观地观察到激振源、摆1、摆2角速度随均匀电子螺旋管输出位移的变化情况。适当调整计算机输出的激振波形,即可调整激振源、摆1、摆2的运动状态。

In the paper, the operating principle of Double Swing Vibration Exciter （DSVE） is introduced, and its simplified physical model is established. Then, linear graph and bond graph methods are introduced, and the linear graph and bond graph models of DSVE are built respectively. After solving respective equation set, the state e- quations about vibration exciting resource, the angular velocity of first swing and the second swing are obtained. The change situation of vi- bration exciting resource, the angular velocity of first swing and the second swing with uniform output displacement of helitron can be ob- served visually. The moving state of vibration exciting resource, the first swing and the second swing can be adjusted by properly adjusting the vibration exciting waveform output from computer.
