| 摘 要： | 本文应用非线性谱分析法，对单点系泊装置在随机海浪作用下的非线性动力响应进行了分析．系统的非线性来源于单锚腿系泊系统的非线性恢复系数．与线性化方法相比，该方法勿需对非线性项进行线性化，从而消除了由于现行化带来的误差，这对于提高计算结果的精度是有益的．

| Abstract: | The nonlinear dynamic analysis of the single point mooring systems underthe action of random sea waves is carried out by means of nonlinear spectral analysis.Thestudy indicates that it is possible to solve nonlinear vibration problems by using spectral analysis directly. It is not necessary to linearize the nonlinear terms in this method so that theerrors introduced by linearization can be eliminated.Therefore,this method will provide aconvenient and accurate tool for solving nonlinear random vibrations. |
