微型仿生飞行器的研究涉及仿生学原理、准稳态气动力和原理样机的研制等。概述了上海交通大学针对昆虫尺度的微型仿生飞行器的新颖的设计和加工方法。该方法确保了零部件空间位置的合理安排,从而减少了零部件的装配难度。具体来说,压电驱动器的设计考虑了电气隔离和装配问题;传动机构与机身整合成一个部件,避免了相互之间的装配。翅脉的纤维方向进行了合理的布置,使得翅膀拥有高强度和高刚度。最终,研制的压电驱动微型仿生飞行器重84mg,翼展35mm,在100Hz的拍打共振频率下可以产生±60°的拍打角度,能产生足够的升力实现起飞。
Micro bionic aircraft research involves bionics, quasi-steady-state aerodynamic and prototype development. The novel design and processing methods of micro-bionic aircraft targeting insects scale are summarized. This method ensures a reasonable arrangement of the spatial position of the parts, thereby reducing the difficulty of assembly of the parts. Specifically, the design of a piezo driver takes into account electrical isolation and assembly issues; the drive mechanism is integrated with the fuselage to form a single unit, eliminating the need for assembly with one another. Wings of the fiber direction of a reasonable arrangement, making the wings have high strength and high stiffness. Finally, the developed piezoelectrically driven micro-bionic vehicle weighs 84mg and has a wingspan of 35mm. It can generate a slant angle of ± 60 ° at a flapping resonance frequency of 100Hz, and can generate enough lift to achieve take-off.
