扑翼飞行器的运动学仿真及气动力分析

在研制的仿生扑翼飞行器的基础上,建立了该飞行器的数学模型,并用MATLAB对简化了的机构进行了运动仿真,模拟出翅翼一个周期内的运动轨迹,同时也计算出了翅翼角速度的变化情况;编写了用条带理论计算升力的MATLAB程序,得出了一个周期内翅翼产生的气动力,同时计算出翅翼在一周期所产生的有效升力,通过选择合适的机构参数使产生的有效升力最大,为结构参数的设计提供指导;该方法可用于仿生扑翼飞行器的设计和分析,验证所设计的飞行器能否实现腾空飞行。

The Simulation and Aerodynamic Analysis of Flapping-Wing MAV

Based on the development of Flapping--Wing MAV, we establish the mathematical model of this aircraft,and simulate the movement of MAV on the basis of mathematical model with the MATLAB, and calculate the angular velocity of the wings;we compile the MATLAB program use the strip theory, and get the aerodynamic force in one flick period,we can quickly calculate the effective aerodynamic force in one flick period with this program,we can get the maximum effective lift by select the suitable parameters, provide the guidance to the design of structural parameters ~ this method can be used for the analysis and design of the Flapping-- Wing MAV,provide the verification whether aircraft can realize fly.
