The invention provides a piezoelectric shunt semi-passive control device for propulsion shafting vibration control and a design method, and the device comprises a piezoelectric shunt circuit which isconnected to a propulsion shaft of a propulsion shafting and rotates along with a propulsion shaft; a power supply device which comprises a static end and a rotating end, wherein the rotating end is connected to the propulsion shaft, rotates along with the propulsion shaft and is electrically connected with the piezoelectric shunt circuit, and the static end is arranged on the periphery of the rotating end and supplies power to the piezoelectric shunt circuit through the rotating end. Longitudinal and transverse vibration of a propeller can be effectively inhibited by adopting dynamic vibration absorption measures, the additional mass is small, and the influence on shafting misalignment is small.

    本发明提供了一种推进轴系振动控制的压电分流半被动控制装置及设计方法,包括:压电分流电路:连接在推进轴系的推进轴上,随所述推进轴旋转;供电装置:包括静止端和旋转端,所述旋转端连接在所述推进轴上,随所述推进轴旋转,并与所述压电分流电路电连接,所述静止端设置于所述旋转端的外围,通过所述旋转端向所述压电分流电路供电。本发明采取动力吸振措施可有效抑制螺旋桨的纵向和横向振动,附加质量小,对轴系不对中等的影响小。
