摘要
深海立管各段之间并非完全刚性连接，本文提出了一种柔性接头的物理模型并建立了整个立管系统的控制方程，研究了柔性接头对立管动力特性和几何非线性静力响应的影响。
Connection between the segments of deep ocean pipe is not completely rigid . A physical model of flexible joint is introduced and the governing equation of total pipe system with flexible joints is developed in this paper. The effects of flexible joints of dynamic characteristic and static geometric nonlinear response of vertical deep ocean pipe are studied. It is helpful for controlling and improving dynamic responses of pipe.
