摘　　要：基于蝙蝠的翼手结构,借鉴了对鸟类飞行的研究成果,建立了仿蝙蝠微扑翼飞行器机翼的折叠扑动模型。采用ansys软件对不同折叠角,翼展比,机翼厚度三种机翼参数的机翼模型进行了模态分析,然后对模态特性较好的一种机翼模型进行静力学特性分析及优化设计。Based on the bat wing structure and drawing on the research results of birds,a folding flutter model of bats flapping wing was built.On this basis,the ANSYS software was used to analyze the modal analysis of several kinds of wing models with different folding angles,wing span ratio and wing thickness.The influence of the three wing parameters on the modal characteristics was preliminarily analyzed,and then the static characteristic analysis and optimization design of a wing model with better modal characteristics were carried out.The structural design of the model has a certain reference value for the wing structure design of flapping wing aircraft.
