| 摘 要： | 把张力腿简化成线性的欧拉-伯努力梁模型，研究了在波浪海流及浮体共同作用下，张力腿的横向非线性涡激振动，采用Galerkin法把非线性的偏微分方程转化为常微分方程，应用4阶龙格-库塔法进行数值求解。结果表明，平台的运动是影响张力腿横向涡激振动的一个重要因素。

| Abstract: | In this paper ,the tendon is modeled as an Euler-Bemoulli beam.It is assumed that environmental forces are due to wave ,current and platform motion. The nonlinear vortex induced vibration of TLP tendon is investigated . And the governing partial differential eqation is reduced to ordinary equation by using the Galekin method, which is solved employing the fourth-order Runge-Kutta method. The numerical results show that the platform motions have great influence on the vortex induced vibration of TLP tendon. |
