摘要: 为分析偏心度对舰载飞机拦阻过程的安全特性的影响,以某舰载飞机为研究对象,建立了拦阻系统动力学模型,研究舰载飞机在偏心状态下的拦阻动力学特性。基于离散的弯折波模型,进行了计及弯折波的对中拦阻动力学仿真,仿真结果与相关标准的试验数据进行了对比,变化规律基本一致。在此基础上进行了偏心拦阻动力学仿真,并研究了偏心度对于弯折波的影响,结果表明:因偏心拦阻,两侧拦阻索初始长度和拉伸速度不同,导致弯折波产生的载荷波动产生差异。当偏心度超过20%时,一侧拦阻索拉力不再呈现波动增大趋势,超过24%时,拦阻索拉力会出现负载和接近破断拉力。随着偏心度的增加,偏心侧的拦阻索承受更多的拦阻冲击载荷,偏心度过大会对拦阻系统的安全特性产生不利影响。

Abstract: In order to analyze the influence of eccentricity on the safety characteristics of carrier-based aircraft in the process of arresting, a complete dynamic model of arresting system of a certain type of carrier-based aircraft is developed to know more about the dynamic property of aircraft in eccentric arrest. Based on the discrete kink-wave model, the simulation of central arrest with kink-wave is conducted. The simulation results are compared with the experimental data of the related standard and it comes out that the basic changing laws are the same. On the basis of central arrest, the dynamic simulation of off-center arresting is carried out, and the influence of eccentricity on bending wave is studied. The results show that due to eccentric arrest, the initial length and tensile speed of the arresting cables on both sides are different, resulting in the difference of load fluctuation caused by kink-wave. When the eccentricity is more than 20%, the tension of one side of the arresting cable no longer shows an increasing trend of fluctuation, and it will be negative and near breaking tension when the eccentricity is more than 24%.With the increase of eccentricity, the arresting cable on the eccentric side bears more arresting impact load, and the eccentricity will produce negative effects on the arresting system when it becomes too large.

Key words: arresting system, dynamics, kink-wave, off-center, arresting cable
