提出了压电复合材料梁的动力响应模型。模型中利用了压电体的正效应和匡威效应。该公式是基于高阶剪切变形理论和帐户的横向应变。压电传感器和致动器可以是表面粘合的或嵌入的，并且可以是连续的或分段的。研究了传感器和执行器的独立行为。数值结果证明了闭环系统主动控制层合梁振动的能力。
A model to demonstrate the dynamic response of piezocomposite beams is presented. Direct and converse effects of piezoelectrics are utilized in formulating the model. The formulation is based on a higher order shear deformation theory and accounts for lateral strains. The piezoelectric sensors and actuators can be surface bonded or embedded and can be either continuous or segmented. The independent behavior of the sensor and actuator is studied. Numerical results are presented to demonstrate the ability of the closed loop system to actively control the vibration of laminated beams.
