采用环氧树脂粘接法制备了由压电层和弹性金属层组成的压电风扇，并将一对碳纤维增强塑料翼梁和聚合物蒙皮连接到两个压电风扇上形成耦合柔性机翼。然后，使用具有相位差的两个正弦电压来驱动耦合的压电风扇。高速数码相机被用来表征的两个自由度（DOF）的机翼的运动和这些结果进行了比较，有限元模型的机翼和耦合的压电风扇。已经观察到，施加到耦合的压电风扇的驱动电压之间的相位延迟起着重要的作用，在控制的扑翼和扭转运动的机翼，这种设置有应用于微型飞行器的扑翼控制的潜力。(c)2008 Elsevier B.V.保留所有权利。
Piezoelectric fans consisting of a piezoelectric layer and an elastic metal layer were prepared by epoxy bonding and a coupled flexible wing was formed by a pair of carbon fibre reinforced plastic wing spars and polymer skin attached to two piezoelectric fans. Two sinusoidal voltages with phase differences were then used to drive the coupled piezoelectric fans. High speed digital cameras were used to characterize the two degree of freedom (DOF) motion of the wing and these results were compared to finite element model of the wing and the coupled piezoelectric fans. It has been observed that the phase delay between the driving voltages applied to the coupled piezoelectric fans plays an important role in the control of the flapping and twisting motions of the wing and this set-up has the potential for application to the control of flapping wings for micro aerial vehicles.
