碳纤维丝缠绕无人机毁伤效能分析

Damage Efficiency Analysis of Carbon Fiber Wire Winding UAV

无人机的应用随着科技的进步迅速发展,但在交通等方面带来的安全隐患却逐渐凸显。基于碳纤维丝缠绕无人机毁伤机理,采用ABAQUS有限元分析软件对不同形状纤维丝缠绕无人机螺旋桨过程进行了数值仿真分析。结果表明,不同纤维丝形状对螺旋桨缠绕的效果不同:对螺旋桨旋转速度的影响,圆形纤维丝缠绕效能较优;而对螺旋桨前行速度的影响,矩形纤维丝缠绕效能更优,该结果可为以后此类反无人机方式中对于纤维丝的选取提供参考。

The application of unmanned aerial vehicle(UAV)has developed rapidly with the advancement of technology,but the safety hazards brought about by traffic and other aspects have gradually become prominent.Based on the damage mechanism of carbon fiber wire winding UAV,ABAQUS finite element analysis software is used to simulate the propeller process of UAV with different shapes.The results show that different fiber wire shapes have different effects on the winding of propeller.For the effect on the rotating speed of propeller,the winding efficiency of circular fiber wire is better.For the effect on the forward speed of propeller,the winding efficiency of rectangular fiber wire is better.This result can provide a reference for the selection of fiber in anti-UAV action in the future.
