摘要: 针对新型舰载机拦阻钩设计初期技术人员关心的拦阻钩结构参数的选型问题,以某拦阻钩为研究对象,基于刚体碰撞理论建立了拦阻钩碰撞反弹动力学模型,研究了拦阻钩碰撞反弹的动力学特性。通过拦阻钩碰撞反弹试验对碰撞模型进行了参数修正,分析和对比了不同缓冲器安装形式下拦阻钩碰撞反弹特性,论述了重心位置、缓冲器油孔半径和初始压强对拦阻钩反弹动力学性能的影响,最后提出了一种拦阻钩缓冲器结构参数优化设计方法并进行了参数优化。结果表明:Ⅱ型缓冲器安装形式更优;随着拦阻钩重心位置距上铰接点长度增大,弹跳高度增大,缓冲器作用力减小;随着缓冲器油孔半径增大,弹跳高度增大,缓冲器作用力减小;初始压强增大,弹跳高度减小,缓冲器作用力增大。

Abstract: Aiming at the selection of structural parameters at the early stage of arresting hook design for new type carrier-borne aircraft, taking an arresting hook as the research object and based on the theory of rigid body collision, we establish the kinetic model of arresting hook collision rebound and study its kinetic characteristics. The collision model parameters are modified via hook collision rebound tests, and the arresting hook collision rebound characteristics with different buffer installation forms are analyzed and compared. The effects of the center-of-gravity position, buffer oil hole radius, and the initial pressure on the properties of arresting hook bounce dynamics are further discussed, and an optimization design method for arresting hook buffer structural parameters is finally proposed and the parameter optimization is performed. The results show that the type Ⅱ buffer installation form is better than other forms. With the increase of the distance between the center of gravity of the arresting hook and the upper hinge point, the rebound height increases and the buffer force decreases. When the buffer oil hole radius increases, the rebound height increases, and the buffer force decreases. However, the rebound height decreases and the buffer force increases with the increase of the initial pressure.

Key words: arresting hooks, dynamics, collision rebound, buffers, optimal design
