“…A beam model can also account for tension and damping in the cable. Thus, the overall structure of the cable is suited to modeling with a beam model; this has been verified by Castello and Matt [1]. Work from the Air Force Research Laboratory confirmed this and further showed that inclusion of shear effects was necessary for accurate cable modeling [2].…”

“…As the cable bends, the wires move against each other, which alters the stiffness of the cable as a whole and is taken into account through careful calculation of the bending stiffness as a function of curvature and wire geometry, including number and arrangement of wires and lay angle. Although there are three terms identifying the bending angles, only two are independent, yielding the relationship (1) where is the shear angle, dw/dx is the angle due to the Euler-Bernoulli bending of the beam, and is the total beam angle due to both bending and shear.…”

The distributed transfer function method is applied to equations of motion for a space flight cable in an ongoing effort to characterize the effects of adding cabling to space structures. A cable model is presented in which the cable is modeled as a shear beam with multiple boundary constraints. Tension in the cable is included and a variety of damping mechanisms are incorporated. Comparison of the model results to experimental data is included, showing that the distributed transfer function cable model with equivalent cable property inputs can bound the range of cable responses and that hysteretic and connection stiffness damping improve the comparison between the model and experimental data.

A cabled beam model is presented in which the cable is modeled as a shear beam attached to an Euler-Bernoulli beam through connections that include both linear and rotational stiffness and damping; the solution is developed through the use of the distributed transfer function method. Tension in the cable is included and a variety of damping mechanisms are incorporated. The experimental data for cabled beams is analyzed and the developed model is compared to experimental data, showing improvement over an existing distributed mass model.

“…The damping ratio of each mode was calculated through modal parameter analysis in the frequency domain, and the damping ratio decreased as the tension increased. The bending stiffness and material damping were estimated based on the maximum a posteriori estimator with a frequency response function [14]. The effective bending stiffness of the cable was calculated based on the simply supported beam theory [15].…”

Wire rope is a complex structure made by twisting wires of various sizes in the longitudinal direction. It is used to support or move engineering structures and is subject to various tensions. Dynamic properties are important parameters to evaluate the resistance to bending deformation and vibration reduction of various structures. They are affected by the magnitude of tension. In this study, an experimental method for measuring the frequency-dependent characteristics of wire rope under tension is proposed. The study analyzed flexural wave propagation employing a vibration transfer function. Experimental results showed that the transfer function of wire rope under tension is affected by tension and bending stiffness. The Newton–Raphson method was employed to numerically measure wavenumbers of the wire rope. The bending stiffness and loss factor were determined from the wavenumbers. Changes in the bending stiffness and loss factor as the tension increased were explained by the dynamic behavior of the structure under tension. As the tension increased, the bending stiffness increased, and the loss factor decreased. Hysteresis analysis indicated that the energy dissipation of wire rope is greater than that of a steel beam due to the friction between the wires. Statistical analysis confirmed a significant correlation between dynamic characteristics and tension in wire rope.
