摘要
通过控制压电复合材料中压电相的分布形式，本文把具有厚度模振动的1－3型压电复合材料和具有扭转模振动的拼接2－2型压电复合材料组合在一起，构成一种混合模式压电材料，并测试了这种压电材料晶片的性能参数。使用这种晶片作的换能器可以根据使用者的要求，单独产生纵波或横波，也可同时产生这两种波。
By controlling the distriution of the piezoelectric Phase in a piezcomposite,that a mixed-mode piezocomposite plate is designed and fabrecaled which is composed of a 1-3 composite with thickness-mode a pieced 2-2 Composite with torsional shear mode. The parameters of the mixed-mode composite plate are tested. According to users requirement, the transducer made from the mixed-mode composite may generate either longitudinal Wave or shear wave, or both waves simullaneously.
