针对飞机战伤抢修中的损伤评估问题,通过数值模拟,研究了战伤对机翼临界颤振速度的影响规律。结果表明,蒙皮损伤对临界颤振速度的影响轻微;骨架结构损伤后,如果损伤在机翼根部,则随着损伤尺寸增大、临界颤振速度开始略有升高,然后单调降低;如果损伤在其中间部位,则临界颤振速度随损伤尺寸的增加单调下降。 Aiming at the problem of aircraft damage assessment during the battle repair, the influence of war damage on the critical flutter speed of wing was studied by numerical simulation. The results show that the skin damage has a slight effect on the critical flutter velocity. If the damage is at the root of the wing, the critical flutter velocity will start to increase slightly and then decrease monotonically as the damage size increases. Damage in its middle part, the critical flutter velocity monotonous decline with the increase of the size of the injury.
