微小型仿生飞行机器人柔性翅的仿生设计与实验研究

Bionic design and experiment on flexible wings of a bionic flying micro-robot

自然界昆虫和小鸟翅膀柔性在提高气动效率和飞行稳定性方面具有很大优势,因而翅的柔性仿生研究将成为目前微小型仿生飞行机器人的重要方向。以昆虫翅膀为基础,进行了柔性翅的仿生机械设计,并重点对其柔性进行了分析和实验研究。实验结果表明,柔性翅的展弦比和前缘梁刚度对升力有较大的影响,其中变刚度前缘梁和大展弦比有益于升力的产生。

The flexure of insect and small bird wings is an advantage for improving aerodynamic efficient and flying stability. So, the bionic study of flexible wings is becoming the main direction of bionic flying micro-robot at the present. The bionic mechanical design of flexible wings is carded based on the mechanism of insect and small bird wings, and specially the flexure is analyzed and studied experimentally. It is concluded that the aspect ratio and rigidity of leading beam have effects on lift force, variety rigidity of leading beam and big aspect ratio are beneficial to the production of lift force.
