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.
