摘要：
A taut multi-point mooring system with a large geometric nonlinearity under wave and current excitation is examined in this paper. The system is found to exhibit local instability and global bifurcations leading to complex nonlinear and chaotic responses. A semi-analytic method based on stability analyses of approximate solutions to the exact nonlinear system is shown to be an efficient predictor of bifurcations and chaos. Thus the method may supplant or significantly reduce the effort of a numerical parametric analysis for the strongly nonlinear ocean system.
