This study aims to simplify the wing model of a biomimetic flapping-wing aircraft and assess the performance of the simplified model through mechanical analysis. The results show that by removing finer parts of the wing veins, the error between the natural frequencies of the simplified model and the actual flapping frequency of dragonflies is within 3%, meeting the design requirements for flapping-wing aircraft. Modal analysis indicates that the simplified wing model closely matches the actual flapping frequency of dragonfly wings, fulfilling the design criteria for biomimetic flapping-wing aircraft. Transient dynamic analysis reveals that the displacement variation of the wing corresponds well with static analysis results, demonstrating the simplified biomimetic wing model's favorable dynamic response characteristics. Thus, the findings of this study hold significant implications for the further design and optimization of biomimetic flapping-wing aircraft.
