| 摘 要： | 为了减轻结构的地震反应,提出了模糊控制算法用于结构的振动控制,控制的目标是减轻结构的位移和加速度响应.设计制作了一款新型的压电变摩擦阻尼器,并将压电变摩擦阻尼器作为控制装置,通过模糊控制算法建立了施加在压电变摩擦阻尼器上的电压与结构的响应关系,量化因子对模糊控制的效果影响极大,通过试算,本文给出了量化因子的计算公式.算例表明,对于安装有压电变摩擦阻尼器的结构,采用模糊控制算法的效果很好.

| Abstract: | Fuzzy control algorithm has been proposed in this paper in order to reduce the structural damage under the earthquake,the control goal is to minimize both the maximum displacement and acceleration responses of the structure.A new piezoelectric friction damper is designed and fabricated,the piezoelectric friction damper is regarded as the control device,interactive relationships between structural responses and input voltages of piezoelectric friction dampers are established by using the fuzzy controller.The... |
