仿生蝴蝶摆动驱动结构的研究

Study on Swing Structure of Bionic Butterfly

使用介电弹性体(DE)薄膜设计了摆动驱动器(DESA),实现摆动运动。设计了同面积不同形状和同形状不同面积的DESA,探究了不同器件结构对DESA摆动驱动性能的影响。结果表明,在同面积的正方形、长方形和等腰三角形中,等腰三角形的最大摆动角度最大;不同面积的等腰三角形中,适中面积的等腰三角形最大摆动角度最大。选取了结构优化的DESA,制作了仿生蝴蝶摆动驱动器,为DESA的设计与应用提供指导。

A kind of Dielectric Elastomer Swing Actuator（DESA）which could swing by using thin film of dielectric elastomer（DE）was designed.How different structures of actuator influenced DESA’s swing performance by devising DESA with same area and different shapes or same shape and different areas were researched.The results showed that the isosceles triangle DESA had the largest swing angle in square,rectangular and isosceles triangle DESAs which had the same area.Among the isosceles triangles with different areas,the isosceles triangle with moderate area had the largest swing angle.The structure-optimized DESA was selected to create a Bionic Butterfly Swing Actuator,which could provide guidance for the design and application of DESA.
