摘要：

The study concerns possible occurrence of instability and bifurcation of vortex-induced transverse oscillations for tension leg platform tethers. The tether is modeled by a simple nonautonomous system with quadratic damping and parametric excitation. Krylov-Bogoliubov-Mitropolsky method was used to predict the stability of the system. Regions of unstable solutions, phase plane portraits and Poincare maps were constructed to illustrate the response of the tether.
