为深入研究环口板加强后T形管节点的抗冲击性能,文章采用试验研究和有限元研究相结合的方法,对未加强和环口板加强T形管节点的抗冲击性能进行了比较研究,旨在确定环口板加强节点受冲击后的典型破坏模态;并通过对变形发展、局部变形和整体变形的区分、冲击力-位移关系曲线、能量耗散等分析,揭示环口板加强节点的抗冲击工作机理,研究环口板的局部加强作用,确定环口板加强方式的有效性,可为管结构抗冲击设计和加固维护提供参考。
In order to further study the impact resistance of T-shaped pipe joints strengthened by annular plate, a comparative study on the impact resistance of the T-shaped pipe joints strengthened with annular plate and port plate was carried out by means of a combination of experimental research and finite element analysis , Aimed to determine the typical failure modes of the ring-plate reinforced joints after impacting. The analysis of the deformation of the ring plate strengthened by the analysis of the deformation development, the distinction between the local deformation and the overall deformation, the impact-displacement relation curve and the energy dissipation analysis The impact mechanism of the joints, the local strengthening effect of the annular plate, the effectiveness of the annular plate strengthening method, and the reference for the anti-impact design and reinforcement and maintenance of the pipe structure.
