摘要
A single degree-of-freedom model of offshore structures with bilinear stiffness is studied for its dynamic response to a nonzero mean, oscillatory fluid flow. Of particular interest is the interaction between the bilinear stiffness characteristic and the asymmetric hydrodynamic drag force. The shooting method and the incremental harmonic balance method are used to determine the periodic steady state solutions. The stability of these solutions is examined by numerical computation of the Floquet multipliers. The stability boundaries are also verified by comparison with the results obtained by direct numerical integration. The cases of stiffness ratio > 1 and < 1 are investigated.
