本文提出了一种基于镧修饰锆钛酸铅陶瓷的光电静电悬臂梁模型。通过对原有的镧修饰锆钛酸铅等效电学模型的修正,得到了连接在两个铜箔组成的平行板上的镧修饰锆钛酸铅陶瓷的新的等效电学模型。在此基础上,建立了光静电悬臂梁的数学模型。通过理论和实验分析了紫外光强度和铜箔长度对光静电悬臂梁偏转的影响。分析结果表明,随着光强和铜箔长度的增加,悬臂梁自由端挠度增大。光伏静电柔性悬臂梁可作为微致动器,具有遥控、清洁驱动等优点。
A model of photovoltaic-electrostatic cantilever beam based on lanthanum-modified lead zirconate titanate ceramic is proposed in this article. New equivalent electrical model of lanthanum-modified lead zirconate titanate ceramic connected to a parallel plate composed of two copper foils is obtained by modifying the original lanthanum-modified lead zirconate titanate equivalent electrical model. After that, the mathematical model of photovoltaic-electrostatic cantilever beam is established. Furthermore, the influences of ultraviolet light intensity and copper foil length on the deflection of the photovoltaic-electrostatic cantilever beam are analyzed via the theoretical and experimental methods. The analysis results indicate that the deflection at the free end of cantilever beam increases with the increase in light intensity and length of the copper foil. The photovoltaic-electrostatic flexible cantilever beam can be taken as a micro-actuator with the advantages of remote control and clean drive.
