摘要:

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。

Abstract:

In order to research the dynamic performance of the arresting hook after touchdown and impacting with the deck when the aircraft is arrested, a full-aircraft assembly model of a certain type of aircraft is developed to conduct dynamics simulation of the landing of the aircraft carrier. The model is updated with the data of arresting hook bounce test, and a more accurate model is obtained. The simulation results are compared with the test results, and the accuracy of the dynamics model is verified. The impact of the deck coating, pitch angle, engaging velocity, sinking velocity and parameters of the arresting hook damper on the dynamics performance of arresting hook bounce is studied. The results show that the engaging velocity has little effect on bounce height and impact force. The bounce height and impact force get larger with the increase of the sinking velocity and pitch angle. The parameters of hook damper almost have no effect on the impact force, but obvious effect on the bounce height.

Key words: carrier aircraft, arresting hook, impact, dynamics, damper
