Inclusion of shear effects, tension, and damping in a DTF beam model for cable modeling

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.
