“…The elastic modulus of the wire cable is generally tension-dependent. Very diverse values of elastic modulus for the steel wire cable have been reported from the experiments in the literatures (Gibson et al, 1968;Kusy and Dilley, 1984), ranging from 90 to 200 GPa depending on the type and construction of cable and the amount of cable tension. Therefore, it was decided to measure the elastic modulus E and the bending rigidity EI of the wire cable by axial pull and transverse bending tests, respectively, at the tension level close to our application.…”

“…The elastic stretch will disappear after the removal of the external load while the constructional stretch will stay. The constructional stretch of a wire cable is recognized as the minimization of the clearances between wires through compression of the core and adjustment of the wires and strands to external tensile load applied on the wire cable (Gibson et al, 1968). The amount of the load, the type of cable construction, the size of core and the length of cable all affect the constructional stretch.…”

The flexural damping of wire cable due to the flexural hysteresis influences the dynamic behavior of slacking wire cables significantly. However, the details of the local model, accounting for the flexural hysteresis between the wire strands, are quite challenging to include in large-scale engineering applications. This paper addresses these difficulties by modeling the flexural damping of slacking wire cables using homogenized Rayleigh damping. By using the nonlinear finite element method and high-speed imaging technique, three aspects of the work were examined. First, the mechanical properties of the slacking cable were identified experimentally. Second, a sample cable was fixed at one end and allowed to vibrate freely at the other end. The shapes of the vibrating cable were captured by a high-speed digital camera and processed by photogrammetry. The cable demonstrated a high flexural damping at zero tension and its damping was measured to be as high as 37.7% of the critical damping. Third, the cable was modeled and analyzed using our newly developed nonlinear curved beam element with the Rayleigh damping. The finite element predictions of the cable motion agree well with the experimental measurement. These predictions demonstrate that the new element is capable of describing the dynamic response of the cable and that the Rayleigh damping is sufficient to model the flexural damping of slacking wire cables.

“…Ringleb FO et al [5] were the first to systematically study the dynamic problems of cables, established the wave equation of stress propagation, and explained the reflection of transverse waves and stress waves in arresting cables. Gibson et al [6][7][8] considered more influencing factors on this basis and established a more comprehensive design theory for arresting cables. ADEC Corporation [9] proposed the wave propagation load theory for calculating the strain dynamic load of arresting cables, which has been applied in engineering.…”

Arresting gear systems play a vital role in carrier-based aircraft landing. In order to accurately understand the process of arresting hook and cable, this study introduces a parameter inversion method to model the arresting cable and applies it to the transient dynamics model of the arresting hook and cable. The feasibility of the arresting cable model and its application to the transient dynamics model of the arresting hook and cable are validated through arresting hook and cable impact tests. The study compares three different models of arresting cables for simulation results and concludes that assuming the arresting cable to be a beam with metal elastic parameters during the modeling process cannot ignore the influence of the cable’s torsional and bending stiffness on the modeling. The study also investigates the dynamic response of the arresting hook during the aircraft arrestment and hooking process and concludes that the stress peak of the hook arm is much lower throughout the entire arrestment process than at the moment of hooking the cable. The study further identifies factors that affect the stress on the arresting hook arm, such as the aircraft’s yaw angle, deck angle, cruising speed, and the initial position of the arresting hook and cable before engagement. The research results have significant implications for improving the design optimization of the structural strength of the functional components of the naval aircraft arresting system and provide theoretical guidance and technical reserves for subsequent related studies.

The danger of Aircraft carrier was in the stage of landing and arrested,which mainly due to the vertical and horizontal speed.To summarize some of the droping block law, in this paper, a certain type of aircraft is studied,the dynamic modeling of the motion process of the airframe, landing gear, tail hook and blocking force is created,then create simulation system including the process of "landing gear droping", "tail hook bouncing"and"aircraft arrested", then the corresponding law of motion is obtained by setting different blocking conditions,which can provide a reference for the protection of the safety of the aircraft when landing and arrested.
