加油机伞抗撞击性能仿真

Anti-Collision Property Simulation of Tanker Aircraft Drogue

以加油机伞为研究对象,建立碰撞动力学分析有限元模型,对加油机伞与加油机受油接头相互碰撞的过程进行了动力学仿真。分析了加油机伞与受油接头之间的撞击力、加油机伞的结构应力以及骨架之间限位钢丝绳的拉力,探讨加油机伞在撞击过程中的动响应规律,并指出了可能导致加油机伞失效的薄弱环节。

By taking the tanker aircraft drogue as a research object, the finite element model of collision dynamic analysis is set up, and the dynamic simulation is performed on the collided process of the tanker aircraft drogue and the oil joint of tanker aircraft. The collision force between the tanker aircraft drogue and the oil joint is analyzed, as well as the structural stress of the tanker aircraft drogue and the tension of the position limit wire ropes among frames. The dynamic response rule of the tanker aircraft drogue in the collision process is investigated. In addition, the research points out the weakness which could result in the nonserviceable of the tanker aircraft drogue.
