Abstract

Arresting gear systems play a vital role in carrier-based aircraft landing. In order to accurately understand the process of arresting hook and cable, this study introduces a parameter inversion method to model the arresting cable and applies it to the transient dynamics model of the arresting hook and cable. The feasibility of the arresting cable model and its application to the transient dynamics model of the arresting hook and cable are validated through arresting hook and cable impact tests. The study compares three different models of arresting cables for simulation results and concludes that assuming the arresting cable to be a beam with metal elastic parameters during the modeling process cannot ignore the influence of the cable’s torsional and bending stiffness on the modeling. The study also investigates the dynamic response of the arresting hook during the aircraft arrestment and hooking process and concludes that the stress peak of the hook arm is much lower throughout the entire arrestment process than at the moment of hooking the cable. The study further identifies factors that affect the stress on the arresting hook arm, such as the aircraft’s yaw angle, deck angle, cruising speed, and the initial position of the arresting hook and cable before engagement. The research results have significant implications for improving the design optimization of the structural strength of the functional components of the naval aircraft arresting system and provide theoretical guidance and technical reserves for subsequent related studies.

通过参数反演法模拟避雷钩和缆绳的瞬态动力学模型
在舰载机起降过程中,迫降装置系统发挥着至关重要的作用。为了准确理解迫降钩和迫降索的运动过程,本研究引入了一种参数反演方法来建立迫降索模型,并将其应用于迫降钩和迫降索的瞬态动力学模型。通过抓钩和缆索冲击试验,验证了抓捕缆索模型的可行性及其在抓捕钩和缆索瞬态动力学模型中的应用。研究比较了三种不同的抓捕缆索模型的仿真结果,得出结论认为,在建模过程中假设抓捕缆索是具有金属弹性参数的梁,不能忽略缆索的扭转和弯曲刚度对建模的影响。该研究还调查了飞机拦阻和挂钩过程中拦阻钩的动态响应,并得出结论:在整个拦阻过程中,钩臂的应力峰值远低于挂上缆绳的瞬间。研究进一步确定了影响阻拦钩臂应力的因素,如飞机的偏航角、甲板角、巡航速度以及阻拦钩和缆绳在接合前的初始位置。研究成果对改进舰载机拦阻系统功能部件结构强度的优化设计具有重要意义,并为后续相关研究提供了理论指导和技术储备。
