摘要: 昆虫通过高频扇翅可以产生很大的升力,相关的非定常空气动力学机理及理论逐渐被人们所认识。基于昆虫的仿生学设计了单个翅膀的扑翼机构,并利用自行设计的测力平台实现了对升力的测量。通过分析测力系统的动态特性及受激励后的响应,得到扑翼产生的周期升力。通过将试验数据与经验公式计算的结果进行比较,得到了升力与扑翼参数的关系,为进一步设计扑翼式微型飞行器提供了依据。

Abstract: Until recently, it has become clear that unsteady mechanism, including high frequency flapping, is necessary for insects to produce enough lift and to keep themselves aloft. Imitating insects, the flapping mechanism is designed, which converts the rotational motion of motor into the two-degree-of- freedom flapping motion of wings. The lift of flapping wings is measured by the force-measuring device. Instantaneous aerodynamic forces are calculated under a set of kinematic parameters. The study can be used as a preparation for the design of micro air robot with flapping wings.
