摘要

在21世纪,人工智能(AI)控制的机器正在占领战场,其中一种是微型无人机。小型无人机武装后,载荷分布和振动特性的研究对其安全运行至关重要。通常情况下,火炮后坐力会传递到微型无人机的平台上,导致平台随火炮不稳定或失效。小型无人机太小,没有空间设置传统的后坐力减少机构。因此,设计一种能代替TNT产生同等爆炸力的机构或替代推进剂是十分重要的。此外,还研究了爆炸对小型无人机振动特性的影响。发现高压气体是TNT材料的最佳替代品,可以减少产生的偏转。这项工作主要集中在确定小型无人机的偏转和频率上。采用压力筒布置,可以改善后坐力作用下的振动特性。

Vibrational Analysis of Mini - Unmanned Aerial Vehicles due to Gun Recoil
In 21st century, battlefields are being occupied by Artificial Intelligence (AI) controlled machines and one of its kind is mini-unmanned aerial vehicles. Upon arming the mini-UAVs, the load distribution and characterizing the vibrational behavior are important for its safe operation. Usually, the gun recoil force gets transferred to the platform of the mini-UAV, leading to instability or failure of the platform along with the gun. Mini-UAVs being too small don’t have the space to set the conventional recoil reduction mechanism. So, it is important to design a mechanism or alternative propellant for achieving the equivalent explosive force instead of TNT. Also, the influence of explosion on the vibration characteristics of the mini-UAV is studied. The high-pressure gas is found as the best alternative to TNT material, for reducing the deflection produced. This work primarily concentrates on determining the deflection and frequency induced in mini-UAVs. By using a pressure canister arrangement, the vibration characteristics under recoil can be improved.
