Abstract分别采用变形参数法、改进的变形参数法及傅里叶分析法确定海洋细长结构参数振动Hill方程的不稳定区,比较三种方法的优缺点,并给出了前三阶不稳定区图像,为张力腿、立管等海洋细长柔性结构的设计提供参考。
Other AbstractThe parametric excitation instability regions of slender flexible cylindrical structures in offshore engineering were analysed by using L-P(Lyapunov-Poincare),modified L-P and harmonic balance method respectively.The results of the three different methods were compared and the chart of first three instability regions was drawn.The results give reference to build up design guidance for Tension leg platform(TLP) tethers and risers.
