摘　　要：基于增加环形叠堆压电陶瓷的输出行程以满足主动减振需求的目的,采用了叉指电极的设计方式,通过ABAQUS软件对压电陶瓷的模型进行有限元分析试验,对不同电极参数分别分析其力学性能。研究结果表明,在驱动电压400 V下,叉指电极环形叠堆压电陶瓷作动器输出位移可以达到普通型作动器的2.4倍,其输出力降低为普通型的44%。叉指电极环形叠堆压电陶瓷的研究为大输出位移的叠堆压电陶瓷作动器的设计提供了一定的理论依据。In order to increase the output stroke of stacked toroidal piezoelectric ceramics to meet the demand of active vibration damping,the design of interdigital electrode is adopted.The finite element analysis of the piezoelectric ceramic model is carried out by ABAQUS software,and the mechanical properties of different electrode parameters are analyzed.The results show that the output displacement of the interdigital electrode ring stacked piezoelectric ceramic actuator can reach 2.4 times of that of the common type at the driving voltage of 400 V,its output power is reduced to 44%of the ordinary type.The study of interdigital electrode ring stacked piezoelectric ceramic provides a theoretical basis for the design of stacked piezoelectric ceramic actuators with large output displacement.
