摘要: 针对舰载机钩偏着舰时拦阻钩沿拦阻索侧向滑摆运动,运用仿真与理论分析结合的方法,通过调整拦阻钩侧向动载荷的振动频率范围,具体研究了飞机机身动载荷特性。结果表明,在2 Hz, 10 Hz,20 Hz 等振动频率附近,机身会受到严重的载荷情况。结论可供机体结构刚度、钩头减摆等性能优化设计参考。

Abstract: The arresting of a carrier-based aircraft in an attitude of yawing and off-center, will cause the lateral swing motion of the arresting hook along the arresting cable. Using the method of the simulation and the theoretical analysis, by adjusting the vibration frequency range of the lateral dynamic loads on the arresting hook, the dynamic load characteristics of the aircraft fuselage is studied. The results show that the severe loads on the fuselage can be caused at the vibration frequency of 2 Hz, 10 Hz and 20 Hz. The conclusions can be used for the optimal design of the structural stiffness and for reducing the hook head swing.

Key words: carrier-based aircraft, arresting hook, swing motion, lateral dynamic load, vibration frequency
