摘要

为了使微小型光学镜头驱动系统满足低能耗、高稳定性以及结构简单的要求

采用新型智能材料IPMC设计了一种微小型的光学镜头致动器

并对其输出力、位移及响应速度等性能进行了研究.根据直线驱动要求确定了瓣形和环形结构; 通过化学还原方法制备了IPMC材料

采用激光切割技术分别制作出5种形状的环形和瓣形致动器

并对其性能进行了测试.利用有限元软件

通过等效热模型分析了致动器的基本性能

结果表明:实验测试与理论分析结果一致

误差率在10%以内; 瓣形致动器的总体位移性能比环形致动器的好; 在3 V驱动电压下两者的位移均大于200 μm; 当内圆半径为2 mm、瓣数为8时

致动器的最大位移与响应速度均最佳.

Abstract

To meet the requirements of low consumption

high stability and simplicity for the optical lens driving system

ionic polymer-metal composite(IPMC)

a new kind of intelligent material is adopted to design a miniature optical lens actuator

and its output force

displacement

and response speed are investigated respectively. For the purpose of linear driving

two kinds of actuating structures

the petal-shaped and annular structures are determined. Then

IPMC is prepared by chemical reduction method and five kinds of petal-shaped and annular actuators are manufactured by laser cutting and their performances are tested. The performances of the actuators with different structure parameters are analyzed using an equivalent thermal model via software FEA. The analytical results coincide well with the experimental ones with error less than 10%

and the displacement performance of petal-shaped actuator is better than that of the annular one. Under actuation voltage of 3 V

both actuators can get displacement over 200 μm. The annular actuator with an inner radius of 2 mm and the petal-shaped actuator with 8 petals achieve better performances in both displacement and response speed.
