| 摘 要： | 通过蜻蜓翅脉的应力松弛实验,验证了昆虫翼的粘弹性特性.并且通过数值拟合,发现可以用标准线性固体模型对其进行描述.通过理论推导,证明昆虫翼粘弹性特性对于昆虫实际高频飞行中提升翼刚度、控制变形幅度、稳定飞行起到很关键的作用.

| Abstract: | To verify insect wings' viscoelastic stress-relaxation,experiments on dragonfly wings' veins were performed.The curve fitting results show that their constitutive behavior can be described with standard linear-solid model.Theoretical deduction results also show that as a consequence of their viscoelastic properties,insect wings are almost two times stiffer in high frequency flapping flight than usual,which is very useful for controlling the range of wing deformation and flight stability. |

| Keywords: | viscoelasticity stress-relaxation constitutive model of insect wings dragonfly |
