摘　　要：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.An active torsional vibration absorber in which an adaptive torque is added to the common dynamic vibration absorber was proposed. In accordance with vibration condition of vibrating object, the control system adjusts the phase, frequency and amplitude of the torque automatically,thus enhances its vibration absorbability and widens its effective frequency band.An experiment system for the absorber and experimental results were also given.
