摘　　要：采用压电材料和粘弹性材料分别作为连杆机构振动主动控制和被动控制的材 料，针对一柔性四连杆机构进行了振动主动控制和被动控制的实验研究。实验结果 表明对于这类具有周期性运动特点的柔性机构振动控制而言，被动控制效果优于主 动控制效果。The paper presents an experimental study on the dynamics response vibration active control and passive control of the elastic four-bar mechanisms. The PID controller is adopted for vibration active control of the dynamics response using the piezoceramic actuators and the piezoceramic sensors. And the visco-elastic material layer is bonded with in the flexible coupler for passive control of the dynamics response of linkage mechanisms. Experiment of real time control of the dynamic response of linkage is carried out. Finally, the experimental results and the main causes influencing the control effects are analyzed.
