摘要
在非运营期间,漂浮软管盘绕在油轮或FPSO的卷筒上,很容易产生变形甚至破坏,漂浮软管的盘绕分析是对漂浮软管进行结构设计、检验校核过程中必不可少的一个环节。首先对模型进行基本假定并确定适合漂浮软管的校核准则,将漂浮软管进行合理的简化处理;然后借助ABAQUS建立模型,并得到漂浮软管主管各层在盘绕弯矩下应力和应变分布情况;最后依据校核准则对主管各层进行强度校核,结果表明主管的各层利用率都满足设计要求,加强钢筋也满足使用中所需的强度要求。
During non-operational period,floating hose coiled on the drum of oil tanker or FPSO,it is easy to deform or even destroy its function,the coiling analysis of floating hose is an indispensable segment in the process of analysis,calculation,inspection and verification of floating hose.Firstly,the basic assumptions of the model and the calibration criteria suitable for the floating hose are determined,and the floating hose is simplified reasonably.Secondly,the model is built on ABAQUS,and the stress and strain of each layer of the main pipe of the floating hose under the coiling moment are obtained.Finally,according to the principle of checking and approving,the strength of each layer of the main pipe is checked.The results show that the utilization ratio of each layer meets the design requirements,and the reinforced bar meets the strength requirements in use.
