仿昆微扑翼飞行器三维整体设计及制造

Monolithic Design and Fabrication of Three-Dimension Biomimetic Flapping-Wing Micro Air Vehicle

MEMS技术在毫米尺度制造中站主导地位,然而在厘米尺度甚至更大尺度下的机构仍是使用许多传统方法制造的,在毫米至厘米尺度范围内存在的介观尺度的器件仍难以制造。针对在这种尺度内的仿生微扑翼飞行器和其复杂微小结构极难手工装配的制造工艺问题,提出了一种三维整体结构的多功能制造方法,即由包含刚性层和柔性层的多片图案化碳纤维层在多个选定的位置处进行叠置和粘结,形成具有多个层间粘结的层压结构,并且在这种层压结构中刚性层之间的柔性层可以挠曲伸展成三维结构。使用这项工艺方法,制造出了一架重约100mg的可从平面结构伸展成三维结构的精密型微扑翼飞行器,研究结果验证了该种设计方法及工艺流程的可行性和有效性,为微扑翼飞行器在工业上规模化制造商提供了崭新的途径和指导意义。

MEMS techniques dominate sub-millimeter scale man-tfacturing,whilea myriad of conventional method exists to produce lager machines measured in centimeters and beyond.So-called mesoscale devices ,existing between these length scales, remain difficult to manufacture. To solvethe problem that the biomimetic flapping-wing micro air vehicle is hard to be assembled by hand because of complexity and minitype, the monolithic fabrication method of three-dimension structures aregiven. In this method, the layers in the structure can include rigid layer and flexible layer. The layers are then stacked and bonded at selected locations to form a laminate structure with inter-layer bonds, and the laminate structure is flexed at the flexible layer between rigid segments to produce an expanded three-dimensional structure. The fabrication of a 100mg flapping wing robotic insect demonstrates this design is feasible, effective, which would suppoort device manufacturing on an industrial scale.
