摘　　要：在借鉴国外工程实践经验的基础上,采用多层管模型来模拟管中管结构,进行了顶张紧式立管管中管结构的非线性时域分析。多层管模型与传统的等效组合模型相比,其主要的优点在于:它可以模拟内外管之间的相互作用,而且可以通过改变扶正器的相关参数,对扶正器的大小和位置进行优化设计,以此保证内外管之间不会发生碰撞和摩擦;此外,文章还对张紧力在内外管之间的分配进行了研究,采用的管中管结构模拟技术对TTR立管在位强度分析技术的发展具有一定的指导意义。Based on experience of foreign engineering practices, the multi-layer tube model is used to stmutate tube-in-tube structure and the nonlinear time-domain of the tube-in-tube structure is analyzed. Compared with the traditional equivalent combined models, the multi-layer tube model has advantages as follows. The interaction between the tubes can be simulated. By changing the centralizer parameters, the size and position of centralizer are optimized in design, which ensures no collision and friction between tubes. The paper also studies the distribution of top tension between the tubes. The structure of the tube-in-tube simulation technology has guiding significance for the development of the strength analysis of the reign of TTR riser technology.
