“微风”(Zephyr7)无人机机翼力学性能分析

Mechanical performance analysis on wing's of Zephyr7 UAV

利用ABAQUS有限元软件对英国的"微风"(Zephyr7)无人机机翼结构进行了静力学分析,重点分析了主梁直径和蒙皮张力对机翼结构抗弯性能的影响。分析结果表明,主梁的抗弯与抗扭性能随着其直径的增大呈几何级数提升,机翼抗弯性能随着其蒙皮张力的增加近似线性增加。

In this paper, structure of Zephyr7 UAV wing will be analyzed with software of ABAQUS. Especially, the effects of the diameter of beam and the pretension of wing skin on the resistance to flexural capacity and resistance to torsional capacity of the wing. The results of analysis show that the resistance of flexural capacity and resistance to torsional capacity of the main beam exponential growth when the diameter increase, the resistance to flexural capacity of the wing growth linearly when the pretension of wing skin increase.
