Dynamic Analysis and Engineering Design of Biomimetic Flapping-wing Flying Robots

摘要

Flapping-wing flying robots are new conceptual air vehicles that mimic the flying modes of birds and insects.They surpass the research fields of traditional airplane design and aerodynamics, and initiate the applications of MEMS technologies on aviation fields. A new dynamic analysis and engineering design method for flapping-wing flying robot is proposed in the background of engineering application. Based on statistics and analysis of structural parameters, kinematical parameters and dynamic parameters of 68 types of different birds, the biomimetie formulas are brought forth and original flying robot design is carded out. According to the biomimetic results, the transmission layout, power scheme and total structure of flapping-wing flying robot are designed, and the dynamic properties of flying robot are studied by dynamic analysis method that include kinematic, aerodynamic and structure dynamic analysis. Then the parameter optimization design is accomplished following dynamic analysis to reach the optimum performance of flying ability. The robot prototype is driven by micro DC motor and polymer lithium battery, and made of carbon fiber fuselage and polyester membrane wing. The total weight of the robot is about 16.5g, wingspan is 200mm, and beat frequency is 10.5Hz. Flying test and wind tunnel experiments verified the effectivity and feasibility of the design. The results of research are helpful to the design, fabrication and application of biomimetic flying robot.
