中文摘要：

分析了飞机着舰拦阻时,拦阻钩初次接触道面碰撞后被反弹的动力学成因,建立了飞机拦阻钩碰撞道面的弹跳模型。研究了下滑轨迹角和甲板角对拦阻钩碰撞反弹角速度和拦阻钩所受冲量的影响,并分别考虑了航母俯仰运动和甲板凸起物对拦阻钩碰撞反弹性能的影响。结果表明：轨迹角约4°时,拦阻钩反弹角速度和其所受冲量随下滑轨迹角呈线性变化;反弹角速度与甲板角的余弦成反比,道面冲量与甲板角余弦的平方成反比;航母向上的俯仰运动和甲板凸起物增大了拦阻钩反弹角速度,凸起物达到一定角度时,机身推拦阻钩的冲量变为拉拦阻钩的冲量。该模型的结果为机身和拦阻钩装置的设计提供了重要依据。

英文摘要：

In this article, a study is made of the collision dynamics of the arresting hook bounce after initial touchdown when the aircraft is arrested, and a collision bounce model is built. The impact of flight path angle and deck angle on bounce angle velocity and the impulse of collision by aircraft and deck are explored. The dynamic performances of bounce angle velocity affected by the pitch movement of the aircraft carrier and deck barrier are analyzed. The results show that when the flight path angle is about 4°, the bounce angle velocity and impulse of collision increase linearly with the flight path angle, the bounce angle velocity is inversely proportional with the cosine of the deck angle; the impulse of collision by aircraft and deck is inversely proportional with the squared cosine of the deck angle; the velocity of collision in the impact direction is increased by the pitch of the aircraft carrier and deck barrier, and the impulse of collision by fuselage changes direction when the deck barrier angle reaches a certain degree. The results of this model provide an important foundation for fuselage and arresting hook device design.
