Abstract A new balanced laminate of piezoelectric fiber composite (PFC) is presented for the improved shear mode piezoelectric actuation of beams. A micromechanics formulation is first presented for determination of its effective electromechanical properties, and then its shear actuation capability is investigated by means of utilizing it for actuation of bending deformation of a smart sandwich beam. The results reveal an indicatively higher shear actuation capability of the present balanced laminate of PFC over that of the monolithic shear piezoelectric actuators, and thus this laminate of PFC may be a potential material for shear piezoelectric actuators in control of flexible structures.

一种用于改进梁的剪切压电驱动的压电纤维复合材料的平衡层压板

摘要 提出了一种新的压电纤维复合材料 (PFC) 平衡层压板，用于改进横梁的剪切模式压电驱动。首先提出了一种微力学公式来确定其有效的机电性能，然后通过利用它来驱动智能夹层梁的弯曲变形来研究其剪切驱动能力。结果表明，与单片剪切压电致动器相比，本发明平衡的 PFC 层压板具有更高的剪切致动能力，因此这种 PFC 层压板可能是用于控制柔性结构的剪切压电致动器的潜在材料。
