Experimental Study about the Performance of the Piezoelectric Friction Damper
Because of its excellent energy dissipation capacity, friction damper has a wide application in engineering structure, while its use is restricted by constant frictional force. Piezoelectric ceramic actuator has electrochromic deformation ability, by the use of this advantage to combine piezoelectric ceramic actuator with friction damper to form piezoelectric friction damper. This paper conducts some experiments, to study the force output performance and response time of piezoelectric friction damper as well as its hysteretic behavior. The results show piezoelectric friction damper has good force output capacity with the input voltage increases, and the hysteretic behavior is stable, which almost has no relevance with loading frequency.
