摘　　要：基于甲虫后翅折叠机理的仿生设计理念,构造一种具有较大折叠率的空间可展机构。分别使用ADAMS和ANSYS软件模拟分析变形翼飞行器的折叠性能和模态特性。ADAMS软件的运动学模拟显示,变形翼在折叠运动时并未发生运动干涉现象;ANSYS软件的分析结果表明变形翼飞行器在不同的振型下可保持最佳的结构稳定性。最后用XFLOW软件进行模拟,结果显示该仿生变形翼能够聚集密集的前缘涡、翅尖涡和后缘涡,从而产生足够的升力克服自身的重量。A biomimetic design concept based on the folding mechanism of beetle hind wings is proposed to construct a spatially deployable mechanism with a high folding rate.The folding performance and modal characteristics of deformable wing aircraft are simulated and analyzed by ADAMS and ANSYS software respectively.The kinematics simulation of ADAMS software shows that there is no motion interference phenomenon when the deformable wing is folded.The analysis results of ANSYS software show that the deformable wing aircraft can maintain the best structural stability under different vibration modes.Finally,XFLOW soft⁃ware is used to simulate the biomimetic deformable wing.The results show that the biomimetic deformable wing can gather dense leading edge vortex,tip vortex and trailing edge vortex,thus producing enough lift to overcome its own weight.
