本文提出了一种主动扭振减振器.它是在普通动力减振器上增加控制力矩,根据被减振物体的振动情况,自动调节控制力矩的大小、相位和频率,从而增加了减振作用和有效频率范围.文中还给出了该减振器的实验系统和实验结果.
In this paper, an active torsional vibration damper is proposed, which adds control torque to the ordinary dynamic vibration damper and automatically adjusts the magnitude, phase and frequency of the control torque according to the vibration of the object to be damped to increase the vibration damping Function and effective frequency range.The experimental system and experimental results of the shock absorber are also given in this paper.
