| 摘 要： | 通过有限元方法探究了机翼上气动力和惯性力对结构变形的影响.研究表明扑翼机翼产生的气动力和惯性力大小在同一量级.机翼惯性力对机翼结构变形具有不可忽视的影响.当机翼处于水平位置时机翼气动力对结构变形贡献最大,同时合力产生的最大变形也出现在机翼水平位置.仿生扑翼机翼结构变形研究为高升力、低能耗扑翼机翼的设计提供了理论指导.

| Abstract: | This paper explored the effects of aerodynamic force and inertial force on the structure deformation of wing by finite element model.The study indicates that the aerodynamic force and inertial force are at the same level.The inertial force of wing has crucial influence on the structure deformation of wing.The maximum deformation was produced by aerodynamic force or resultant force when wing was located horizontally.The study of the structure deformation provides a technical guide for design and optimization of flapping-wing. |
