为了使舰载机能安全顺利地在舰上回收,分析了飞机着舰拦阻时,拦阻钩撞击甲板悬索后钩组件上转的动力学成因。在考虑弯折波的基础上,分析了飞机在偏航着舰时拦阻钩发生横向摆动的成因,建立了偏航着舰时拦阻钩上转和横摆动力学模型。研究了偏航角和钩索之间的摩擦系数对拦阻钩横向摆动的影响,并考虑了轮胎压索以及钩臂与铰接点轨迹之间的初始夹角对拦阻钩上转性能的影响。结果表明:因偏航着舰,挂索后拦阻钩上转过程中出现了横向运动;横向运动的最大摆角随偏航角和摩擦系数的增大而增大;轮胎压索导致悬索弹起,拦阻钩到达时,悬索的高度对拦阻钩上转运动没有明显的影响,但是悬索过高会使拦阻钩有弹跳脱钩的危险。

In order to recycle the carrier-based aircraft safely, a research is conducted on the dynamics explanations of the upswing motion of an arresting hook unit immediately following engagement of an arresting cable. The dynamics explanations of the lateral swing motion of the hook in yaw condition are explored, with the kink-wave that travels along the arresting cable considered. Upswing and lateral swing dynamics model of an arresting hook in yaw condition is established. The impact of yaw angle and friction coefficient between hook and cable on the lateral swing motion of arresting hook is studied. The dynamics performances of upswing affected by arresting cable being depressed by passage of aircraft wheels and the first angle of hook suspension with respect to the path of the hinge point are analyzed. The results show that the lateral component of the motion of hook is nonzero in yaw condition. The maximum angle changes of lateral swing motion get larger with yaw angle and friction coefficient between hook and cable. After depressed, the cable rears up to a height. The height has little effect on the upswing motion, but if the height is too high, there is a risk that the contact between hook and cable will be lost.
