Novel Structure for Waveform Control of Twin Rotary Flowrate Valve Controlled Vibration Exciter

For improving the vibration waveform amplitude and controlling the vertical shift flexibly, a novel structure for waveform control of twin rotary flowrate valve controlled vibration exciter is proposed. Based on the novel principle, the governing equations of the vibration waveform is derived. Furthermore, the experimental verification is carried out with the prototype of a new vibration exciter. ...
