The equations of motion of a suspended, inextensible cable in
the absence of damping are studied. A method is developed and
illustrated for determining the frequencies and mode shapes for small
oscillations about the equilibrium configuration.
With the introduction of a new variable, the fourth order equation
governing tangential displacement...
Short non-flexible elements of cable were driven harmonically
in water while constrained by springs. The cable elements were observed
to oscillate at approximately the Strouhal vortex shedding
frequency. Damped resonance occurred near the point where the natural
frequency and the Strouhal vertex shedding frequency were equal.
Transverse oscillation amplitudes greater...
Computer oriented techniques and procedures are presented for the analysis of single and multiple cable systems. Application is made to a two-point mooring system influenced by surface and subsurface hydrodynamic loading. The effects of the various parameters are presented and the numerical method is compared to exact solutions obtained from...
The nonlinear dynamic analysis of cable and membrane structures
is presented in this study. Attention is given to the nonlinearities
arising from large displacements, from nonlinear stress-strain
relationships and from nonconservative loadings.
The finite element method is used to model the cables and
membranes. Curvilinear geometries of the elements are...
Cables used in the ocean are often constructed of helically wound
wires or strands. Tension in the cable induces torque and/or rotation
about its longitudinal axis. A method is presented to determine the
tension, torque, location and angular orientation of points on the
cable centerline, using a shooting method algorithm...
