FREE VIBRATIONS OF CABLE IN THREE DIMENSIONS

The results of an extensive analysis of the three-dimensional free vibration of a single span cable, using nonlinear finite elements, is presented. The method provides excellent results throughout the spectrum of end conditions and geometric nonlinearity. For a homogeneous cable of constant cross section, the nonlinear equilibrium position and the natural frequencies were shown to depend only on the end conditions and the stiffness-to-weight ratio. It has been demonstrated that results of engineering usefulness can be obtained from plots made for a typical value of the stiffness-to-weight ratio since realistic deviations from this value result in only minor changes in the frequencies. An empirical formula based on static calcuations, which gives a good approximation to the lowest natural frequency, has been presented. /Author/
