| 摘 要： | 实验研究表明,昆虫(如鹰蛾)在作特定的飞行时,它的翅尖作8字形运动,并伴有翅翼的翻转.为了设计微扑翼飞行器的翅翼机构,深入研究了8字形曲线的形状谱特征,发现了形状谱及其相似度计算公式无法有效识别不同8字形曲线的问题.针对该问题,提出了一种基于形状谱提取8字形连杆曲线特征参数和区分8字形连杆曲线的新方法,并用此方法进行了仿鹰蛾微扑翼飞行器翅翼机构的运动设计.

| Abstract: | The experimental studies have made a conclusion that the wingtip of insect usually undergoes an 8-shape curve with the wing rotating when it is flying. For the purpose of designing flapping mechanism, the Shape Spec- trum of 8-shape linkage curve is studied extensively. It is found that the conforming function widely used at present does not work well in distinguishing the 8-shape linkage curves. Based on the theory of Shape Spectrum, a set of pa- rameters is proposed to characterize 8-shape linkage curve, and a new conforming function is given. In addition to these, a database is established by using these characteristic parameters for designing the flapping-wing of micro air ve- hicles. The main idea of this paper is demonstrated by an example. |
