| 摘 要： | 基于内孤立波mKdV理论,采用时域有限位移运动方程,结合改进的Morison公式研究了两层流体中内孤立波与张力腿平台(TLP)的相互作用,针对东沙群岛南部海域附近某实测内孤立波特征参数,计算并分析了国际船舶结构力学会议提供的张力腿平台(ISSC-TLP)的内孤立波冲击载荷与运动响应,以及张力腿的张力变化特性.结果表明,内孤立波将对张力腿平台产生突发性的冲击载荷以及大幅度水平漂移运动,并使得张力腿的张力显著增大.

| Abstract: | Based on the mKdV theory of internal solitary waves in a two-layer fluid,a theoretical model for analyzing the interaction of internal solitary waves with tension leg platforms was presented by using coupling motion equations of six degrees of freedom for the floating body combining with the modified Morison formula.The observational data near the Dongsha Island were used as the characteristic parameters of the internal solitary wave,the characteristics of hydrodynamic load and motion response,as well as te... |
