光驱动执行器可以引入远程驱动和控制效果，而无需任何硬线连接。在这项研究中，光致伸缩（光压电）特性和光致变形的分布式光致伸缩光学执行器的研究和设计参数的参数化研究进行。讨论了光致伸缩（光压电）效应（光伏效应和匡威压电效应的结合）引起的光致形变，给出了光致形变的二维本构关系。建立了分布式驱动器光致变形效应引起的二维等效控制力和力矩的数学模型，推导了系统的控制方程。静态和动态的应用进行了讨论，并进行设计参数的仿真研究和评估。
Optically driven actuators can introduce remote actuation and control effects without any hard-wire connections. In this study, photostrictive (opto-piezoelectric) characteristics and photodeformation of distributed photostrictive optical actuators are investigated and a parametric study of design parameters is conducted. Photodeformation induced by the photostrictive (opto-piezoelectric) effect (a combination of the photovoltaic effect and the converse piezoelectric effect) is discussed and its two-dimensional (2D) constitutive relations are presented. 2D equivalent control forces and moments induced by the photodeformation effect of distributed actuators are formulated, and system governing equations derived. Static and dynamic applications are discussed, and simulation studies of design parameters are conducted and evaluated.
