基于ABAQUS的下闸首结构应力变形三维非线性有限元分析

摘要

In view of the complex problems of the structure and stress of the lower lock head of Dongfei River,the displacement and stress field under different working conditions are analyzed by 3-d nonlinear finite element ABAQUS software.Calculation results show that using three dimensional finite element analysis software for complex structure has more advantages than in the past the traditional two-dimensional graphic calculation analysis method,the horizontal displacement and vertical displacement of lower lock head of Dongfei River can satisfy the requirements of specification.The results of three-dimensional finite element analysis can be more intuitive and accurate to reflect the overall strength and displacement of the lower lock head, which can provide a basis for evaluating the security state of the structure.%针对东淝河船闸下闸首结构及受力复杂问题,采用三维非线性有限元ABAQUS软件,分析研究下闸首在不同工况下的位移及应力场.计算结果表明,针对复杂结构采用三维有限元分析软件较以往传统的二维平面计算分析方法更有优势,东淝河船闸下闸首的水平位移和垂直位移均满足规范要求.三维有限元分析结果能比较直观、准确反映下闸首整体强度和位移状况,为评价结构安全性态提供依据.
