摩擦阻尼器因其良好的耗能能力而在工程结构中广泛的应用。压电陶瓷驱动器具有电致变形能力,尽管变形位移很小,但若是其变形被约束后,在电场的作用下则能产生很大的驱动力。本文利用两组PZT驱动器分别与摩擦阻尼器组合制成PZT智能摩擦阻尼器,测试该两组驱动器的响应能力以及PZT摩擦阻尼器的响应时间。
Because of its excellent energy dissipation capacity, friction damper has a wide range of applications in engineering structure. Piezoelectric ceramic actuator has electrochromic deformation ability. If the deformation has been constrained, it can produce a great driving force under the influence of the electric field, though the deformation displacement is small. In this paper, it combines two of PZT actuators with friction damper respectively to make a PZT smart friction damper and tests responsiveness of the two actuators and response time of the PZT friction damper.
