摘要
该文基于非线性有限元软件ABAQUS,针对自升式海洋平台结构特点,提出了"板-梁"耦合技术,用以简化建立自升式海洋平台的结构模型。以平台典型的单K和双K节点为研究对象,基于"板-梁"耦合模型及板壳模型分析了其碰撞性能,同时比较验证了"板-梁"耦合技术的可靠性。研究结果表明,"板-梁"耦合模型在碰撞冲击载荷下的结构损伤变形、碰撞力和能量吸收等动态响应与板壳模型结果一致性较好。该文研究成果可以为大型平台结构整体碰撞性能分析提供技术支撑。
The ＂plate-beam＂ coupling technology is proposed based on the nonlinear finite element software ABAQUS for building the structural model of Jack-up platform.The collision performance between the shell models and the ＂plate-beam＂ coupling models are compared,and the results indicate that the damage deformation,impact force and energy absorption of the ＂plate-beam＂ coupling model are in good agreement with the shell model.The results can provide technical support for the analysis of large-scale platform collisions.
