摘要

钢悬链式立管是目前应用最为广泛的一种深水立管形式，基于现有的钢悬链式立管出平面运动理论，提出了一个钢悬链式立管出平面涡激振动模型。该模型实现了钢悬链式立管涡激振动与刚体转动的耦合。基于该模型在CABLE3D基础上二次开发分析程序CABLE3D_ Rotation模拟立管的出平面涡激振动。分析发现，考虑流固耦合作用的立管出平面涡激振动为一变频变幅的随机振动，对立管中下部响应影响较大，在立管动力分析中不应忽略。随后通过试验证明了钢悬链式立管动力响应中存在刚体转动模态，验证了提出的考虑流固耦合的非线性刚体转动模型的准确性。

Abstract

Steel catenary riser (SCR) is one of the most widely used forms of deep-water risers. Based on the existing theory, an out-of-plane vortex induced vibration (VIV) model of SCR was proposed. The coupling of VIV and rigid rotation was considered in this model. Based on the proposed model, the analysis program CABLE3D_ Rotation was developed to simulate the out-of-plane VIV of SCR. The study showed that considering fluid-structure interaction (FSI), the out-of-plane VIV of SCR is a random vibration with time-varying frequency and amplitude; the effects of FSI on responses of the middle and lower parts of a SCR are larger, FSI can’t be neglected in SCR dynamic analysis. The test results showed that there is a rigid rotation mode in dynamic responses of SCR; the correctness of the proposed nonlinear rigid rotation model considering FSI was verified.
