A new type of the PZT driving device to realize the planar movement by using the bimorph oscillator as the driver was presented. 摘要采用双压电晶片振子为移动机构的驱动源，提出可以实现二维平面移动的新型压电驱动机构。
By numerical calculation and analysis of bimorph and unimorph piezoelectric beams, the difference and applicable scope between linear and nonlinear models were found. 通过对双压电晶片梁和单压电晶片梁的数值计算及分析得到线性与非线性模型之间的差别和适用范围。
