SIMULATION ANALYSIS OF ARRESTING PROCESS FOR CARRIER AIRCRAFT CONSIDERING KINK-WAVE1)

• 摘要: 为研究弯折波现象和分析弯折波对舰载机拦阻过程的影响,基于Euler-Bernoulli非线性梁理论,建立了考虑弯折波的拦阻索离散模型。对拦阻过程进行数值仿真,仿真结果表明,弯折波在整个拦阻过程均存在,使得拦阻钩载荷出现波动,且这种波动在拦阻初期最为剧烈,之后逐渐减弱。弯折波的存在明显缩短了拦停时间和拦停位移,还使得拦阻索拉力的最大值更大。此外,奇数重弯折波与偶数重弯折波在传播方向、拉力角和弯折波平均波速等方面均表现出明显的不同。

Abstract: Based on nonlinear Euler-Bernoulli beam theory, a discretized model of the arresting cable considering the kink-wave is developed to study the phenomenon of the kink-wave and analyze the influence of the kink-wave during the arresting process of carrier aircraft. The numerical simulation result of the arresting process shows that the kink-wave exists in the whole arresting process. The hook load fluctuates due to the kink-wave. This fluctuation is most intense at the initial period of the arresting process. Then the fluctuation gradually attenuates. The existence of the kink-wave significantly shortens the stopping time and stopping displacement, and also makes the maximum value of the arresting cable tension larger. In addition, there are obvious differences in propagation direction, angle of cable tension and average velocity of the kink-wave between the odd and even numbered kink-waves.
