考虑挂钩初期弯折波在拦阻钢索中的传播以及拦阻机液压阻尼作用,建立舰载机拦阻着舰动响应分析数学模型,研究舰载机在不同着陆重量与不同啮合速度组合下着舰时的钩载随时间以及冲程的变化规律,并以美国MK7-3拦阻机为例进行模拟分析,计算表明,文中建立的模型和分析结果具有良好的精度,可为飞机-拦阻机相容性及舰载机的拦阻提供有益的参考。
Carrier aircraft arrested deck-landing dynamic problem based on kink-wave was discussed. Studying the process of cartier aircraft arrest deck-landing and referring the existing mathematic models of cartier aircraft and arresting gear, the mathematic model of kink-wave transmitting was built. Considering kink-wave transmitting in arresting cable and the hydraulic damping effect of arresting gear, the mathematic model of carrier aircraft arrest deck-landing dynamic analysis was built. By these mathematic models, the relationship between arresting hook load and the rtmout distance or time with the variable aircraft weight and variable contacted velocity were simulated. The maximum arresting hook load of model simulation value was compared with test value using the MK7-3 arresting gear. The results indicate that the models presented have fine precision, which can supply available references for aircraft-arresting gear compatibility and carrier aircraft arresting.
