摘要: 综述了压电材料在智能结构形状和振动控制中的应用．基于大量国内外有关压电介质的文献，对在分布的压电材料的表面建立力学特性与电学特性的一一对应关系，以及与之对应的分布感测、分布控制理论和混合控制理论，作了全面阐述．首先概述了研究压电材料的重要意义，然后介绍了压电本构关系和有关压电板壳的力学理论和控制理论．着重阐述了研究压电结构的数值方法与实验．展望了该领域今后的研究方向．Abstract: This paper summarized the applications of piezoelectric materials on shape control and vibration control of smart structures. The relationships between mechanical and electrical properties on the surface of distributed piezoelectric membrane and the theories of distributed sensitivity/control and hybrid control were described. At first, piezoelectric materials and their phenomenon were elucidated; then the piezoelectric constitutive relations and the theories of mechanics and control on piezoelectric plate ...
