空中加油机给油插头撞击受油机结构数值仿真研究OA

In the process of air refueling,the oil joint of the tanker aircraft may break away from the air refueling hose and collide with the receiver aircraft,which can lead to significant damage to the receiver aircraft components and endanger the safety.In order to ensure the anti-impact ability of the receiver aircraft components,the dynamic simulation of the collision process between different parts of the receiver aircraft and the oil joint is carried out by using a transient nonlinear impact analysis,and the effects of different impact attitudes and different impact veloci-ties of the oil joint on the impact damage of the receiver aircraft components are studied.The results show that the vertical impact of the oil joint head is more destructive than that of the oil joint tail.When the oil joint head impacts the windshield or the upper wall panel vertically,the center of the leading edge is the weakest location for the verti-cal impact.It is also found that the stiffness matching between the structural components should be considered in the anti-impact design of the receiver aircraft.
