摘要
立管强度校核一般要求进行组合应力校核与椭圆度校核,由于立管受力的复杂性,目前尚没有计算立管应力、变形的通用公式,基于有限元分析软件abaqus/aqua模块,编制环境载荷的INP文件,分析了环境载荷对立管应力变形的影响,为工程实际中海洋立管强度校核提供了理论基础。
The intensity check of riser must include combined stresses and ovality.As the stress of riser is complex,there is no common formula for calculating the stress and strain of riser.This paper writes the input file of the environment load based on ABAQUS/aqua,the impact of environment load on riser is analyzed.The result provides a theoretical basis for the intensity check of riser.
