Abstract

Abstract: A mechanical model of simple subsea spools was developed according to marine working environment.A simple formula containing a dynamic coefficient was obtained by the maximum seismic acceleration approach.The dynamic equation was numerically resolved by using the data of earthquake waves.The numerical calculation results verified by the finite element method can be employed to determine the dynamic coefficient.

摘要： 根据海底管道铺设环境的实际情况,建立了海底管道简单弯管的力学模型,并用地震最大加速度法求得包含1个动力安全系数的工程设计计算公式。用加速度时程曲线法对弯管的动力学方程进行了数值计算,同时使用有限元软件验证了数值计算结果,为动力安全系数的选择提供了依据。
