摘　　要：海洋管线广泛用于海洋工程领域,是一种运输石油和天然气的重要挠性构件,在波浪、流等动力因素作用下容易产生显著的动力响应。本文在忽略转动惯量和剪切应变的情况下介绍了2种用于海洋管线静动力分析的模型:局部坐标下的通用解析模型和三维凝聚参数模型。采用四阶龙格-库塔法积分运动方程,并计算一个实例验证了第二个模型,此模型还可以用于系泊缆、刚性或柔性立管等细长结构的动力分析。Submarine pipelines are widely used in the offshore engineering field. They are important flexible structures for the transportation of oil and gas,which are easy to have significant dynamic response due to dynamic factors such as waves and flow. Two models neglecting rotary inertia and shear deformation effects for static and dynamic analysis of submarine pipelines are present in this paper： universal analytic model of local coordinate and three-dimensional lumped parameter model. The Fouth Runge-Kutta method is adopted to integrate the motion equation. One example is also gived to verify the second model. The model can aslo be used for the dynamic analysis of slender stuctures such as mooring cables, rigid and flexible risers.
