为了解舰载飞机着舰时拦阻钩碰撞甲板后被反弹的动力学性能,以某舰载飞机为研究对象,建立了全机着舰动力学模型和拦阻钩碰撞甲板的碰撞模型,进行了全机着舰动力学仿真,通过拦阻钩碰撞反弹试验对碰撞模型进行修正,得到了更加准确的碰撞模型。将仿真结果与试验结果进行对比,验证了模型的准确性。研究了甲板涂层、俯仰角、航向速度、下沉速度和拦阻钩阻尼器参数对拦阻钩反弹动力学性能的影响。结果表明:航向速度对反弹高度和碰撞力几乎没有影响;随着下沉速度和俯仰角的增加,反弹高度和碰撞力也增加;拦阻钩阻尼器参数的变化不会影响碰撞力,但是对反弹动力学性能会产生明显的影响。
In order to understand the dynamic performance of ship-based aircraft when it hinder the rebound after hook crash deck, a full-aircraft launching kinematics model and a collision model of arresting hook crash deck were established with a study of a carrier-based aircraft. The simulation of the ship-launching craft corrects the collision model through the barricade hook collision rebound test, and obtains a more accurate collision model. The simulation results are compared with the experimental results to verify the accuracy of the model. The effects of deck coating, pitch angle, heading velocity, subsidence velocity and damped hook damper parameters on the rebound kinetic performance of barred hooks were studied. The results show that the heading speed has almost no effect on the rebound height and the impact force. The rebound height and the impact force increase with the increase of the sinking velocity and the elevation angle. The changes of the damped hook damper parameters will not affect the impact force. However, Learning performance will have a significant impact.
