摘要
为实现对无人机回收系统的可靠设计,需对无人机回收过程开展准确的动力学行为仿真。首先提出了一种网线复合式回收方案,通过弹性绳和涡卷弹簧阻尼器提供可变阻尼来实现无人机无过载无损回收。然后,基于Adams动力学仿真软件搭建了中小型固定翼无人机机背天钩挂线-机鼻倒钩装网复合式回收系统动力学仿真系统,仿真分析了弹性绳不同直径和材料弹性模量对无人机回收效果的影响。研究表明,绳直径和弹性模量与提供的阻尼成正比,但只有当最大加速度不超过10g,且撞网速度较小时才能实现无人机的无过载无损回收,最终在绳直径和弹性模量分别为4.0 MPa和20 mm时回收效果最好。
To achieve reliable design of the UAV recovery system,accurate dynamic behavior simulation of the UAV recovery process is required.Thispaper initially proposes a net-cable composite recovery scheme,which utilizes elastic ropes and spiral spring dampers to provide variable damping,thereby achieving overload-free and non-destructive recovery of UAVs.Subsequently,based on Adams dynamic simulation software,a dynamic simulation system for a composite recovery system of small and medium-sized fixed wing UAVs was established,encompassing the back sky hook hanging line and the nose net inverted hook.The simulation analyzed the impact of different elastic rope diameters and material elastic moduli on the recovery effectiveness of UAVs.Research indicates that the rope diameter and elastic modulus are directly proportional to the provided damping.However,overload-free and non-destructive recovery of UAVs can only be achieved when the maximum acceleration does not exceed 10g and the final velocity is low.Ultimately,the best recovery effect is achieved when the rope diameter and elastic modulus are 4.0 MPa and 20 mm,respectively.
