环口板加强T型管节点抗冲击性能分析
|
摘要
对环口板加强T型管节点的抗冲击性能进行了分析,从节点的受力和破坏模式方面进行了论述,运用有限元软件对环口板加强T节点进行了建模并进行了参数分析,得到不同参数对节点抗冲击能性能的影响规律,提出了环口板加强T型节点的抗冲击承载力计算公式。
The impact resistance of the T-tube joints strengthened by the ring-shaped plate is analyzed. The stress and failure modes of the joints are discussed. The finite element software is used to model the T-nodes of the ring-plate reinforcement. Parameter analysis,the influence law of different parameters on the impact energy performance of the joint is obtained,and the calculation formula of the impact bearing capacity of the T-node strengthened by the ring plate is proposed.
