摘　　要： 分析了多次压电效应的产生过程,利用有限元法得出了压电陶瓷在外力作用下的多次压电效应仿真分析结果。采用PZT-5叠堆进行了正压电效应开始的多次压电效应的实验研究,通过改变PZT-5叠堆的边界条件进行信号的解耦和分离,得到了实验结果。实验数据表明,二次逆和三次正压电效应均与所施加的外力具有线性关系。 The process of multi-piezoelectric effect generation is analyzed. Through the method of finite element analysis, the results of multi-piezoelectric effect of the piezoelectric ceramics under applied force are obtained. Experimental research of secondary and tertiary piezoelectric effect starting from the direct piezoelectric effect is performed through PZT-5 stack. The signals of secondary converse piezoelectric effect and tertiary direct piezoelectric effect are decoupled and separated by changing boundary conditions of PZT-5 stack. The experimental data shows that the output of secondary converse piezoelectric effect and tertiary direct piezoelectric effect is linear with the applied force.
