| Abstract: | In this paper, by utilizing piezoelectric ceramic actuator,s characteristic of piezoelectric and frictional damper's characteristic of that the magnitude of friction force is detedrined by the magnitude of its clipping force, smart piezoelectric-friction damper is presented. Firstly,the primary compound structure of laminated piezoelectric ceramic actuator and pall frictional damper is present. Secondly, the calculating method of piezoelectric-friction damper's adjustable clipping force is presented and the influence of damper's figure parameter is analyzed. Finally,two kinds of piezoelectric-friction dampers with the adjustable frictional force and imitated viscous characteristic are designed concretely. |
