针对谐振型压电陶瓷驱动器的动态非线性，建立了一个数学模型来定量描述驱动器输入与输出的非线性关系，借此可以定量地分析其动态非线性的大小；并利用此模型对PZN-PZT悬臂梁式双晶片弯曲驱动器动态非线性进行了实验分析，实验结果表明此模型对驱动器动态非线性定量分析效果良好。

As to the dynamic nonlinearity of resonant piezoelectricactuators，a simple model is set up to quantify the nonlinear relation between input and output of actuators in this paper．So the dynamic nonlinearity of actuators can be quantitatively studied by it．In addition，taking an experiment for example，the model is applied to research the dynamic nonlinearity of a PZN-PZT bending-mode piezoelectric bimorph cantilever actuator．The experimental result shows that the dynamic nonlinearity of piezoelectric actuator can be quantified effectively by this model．
