哈尔滨工业大学工学硕士学位论文 摘要 蜻蜓是地球上最古老的生命之一，经过了数十亿年的进化，其具有其他 生物所不能比拟的优异的飞行能力。随着近年来仿生技术的发展，人们己经 开始探索制造仿蜻蜓的微型飞行器。在制造这种飞行器之前，首先要对蜻蜓 的飞行机理进行研究。 在本研究中首先利用流体分析软件FLUENT进行了前翅拍动时的流场 分析，并计算得到翅翼所获得的升力。然后基于蜻蜓真实的翅翼样本，利用 相应CAD软件分别建立了前、后翅翼的几何结构模型，并通过选择适当的 单元类型及设定特性参数，完成三维仿蜻蜓前、后翅翼的有限元建模，将计 算所得到的升力作为载荷使用有限元软件ANSYS进行了静力学分析，将由 于受力所带来的翅翼变形带回流场计算中，进行流固耦合计算，并探讨了蜻 蜓扑翼频率、扑翼形式、升力之间的关系。 其次，在对蜻蜓飞行机理研究的基础上，设计、制造了一台用于模拟蜻 蜓飞行时翅翼拍动的试验装置。该装置中振动源选择压电陶瓷，控制系统选 择使用LabVIEW编写。使用电容测微仪、加速度传感器对试验装置进行了 实际工作情况的测试，测试结果表明能够不仅实现模拟蜻蜓单翅拍动，还能 实现双翅同时拍动。 关键词流场分析：仿生：蜻蜓：拍翅频率：试验装置 -I-

哈尔滨工业大学工学硕士学位论文 - II - Abstract Dragonfly is one of the most ancient lives on the earth, through billions years of evolution, it has excellent flight ability that other lives can't compare with. Along with biomimetic technical development in recent years, people have already started to investigate the micro-aircraft which imitates dragonfly. We need to carry out research on the principle of dragonfly flight before making this kind of aircraft. In this thesis, liquid field of forewing flapping is analyzed by using FLUENT software, and the lift force is calculated, then, based on the real structure of the forewing and hindwing of dragonfly, the plane geometric model of biomimetic wings is created using some CAD software. The three-dimensional finite element models of biomimetic wings are built by choosing suitable element types and characteristic parameters. FEA software ANSYS is used to conduct calculation of the wings’ deflection under static force, which use the lift force computed before as load, take the deviation of forewing which made by lift force to liquid field of forewing flapping analysis, and manual iterative liquid-solid coupling compute. The relationships among the dragonfly flapping frequency, flapping form and lift force are discussed. Second, base on the research on dragonfly flapping fly theory, a set of experimental apparatus is designed and manufactured which is used to simulate dragonfly flapping. The flapping resource of the apparatus is PZT, and control system is programming by LabVIEW, capacitance micrometer and acceleration sensor are used to test the actual working status of the experimental apparatus. The result of test shows that the apparatus not only can realize simulate single dragonfly wing flapping, but also realize double wings flapping at same time.
