Abstract:

In order to analyze the complex dynamic performance of an aircraft arresting cable, a rigid-flexible coupling dynamic model of an aircraft arresting cable system is built with the finite element method. The arresting cable is established as an elastic space wire rope, and the hydraulic energy absorbing system and deck damper sheave system is discretized into a beam element with elastic and damping properties to fit linearly in the system and act as constraints to the transmission cable. The contact between the flexible steel cable and the rigid support is considered in the collision dynamics model which is established with the finite element analysis software LS_DYNA. A simulation test is performed with the model. The results show that continuous shock attenuation of stress waves exists in the cable between the aircraft hooking point and the deck sheave when the aircraft hook engages the arresting cable, and that the arresting force achieves its extreme value when the first reflection waves from the deck sheave reach the engagement point of the hook.
