Abstract

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, firstly to study the force output performance, response time of ordinary piezoelectric friction damper, hysteretic behavior as well as its energy dissipation, secondly to study the performance of the Pall-typed piezoelectric friction damper which is consisted by Pall-typed frictional damper and piezoelectric ceramic actuator. The results show piezoelectric friction dampers have good force output capacity and they increase with the input voltage increases; the dampers have a quick response and a short response time; the hysteretic behaviors are stable, which almost has no relevance with loading frequency.

Keywords: Piezoelectric friction damper, Piezoelectric ceramic actuator, Pall damper, Response time, Hysteretic behavior.
