摘　　要：给出薄壁容器大开孔的模型,采用不同数目和不同焊接方位筋板的新型补强结构对此薄壁容器大开孔进行补强,通过对不同补强模型的有限元计算和应力分析,确定适合条件的筋板数目和筋板方位,然后对此补强结构进行屈曲分析,以校核其稳定性。A model of thin - wailed pressure vessel with a large opening is given. The new reinforce- ment methOds are carried out for the large opening with different number of ribbed plates and different welding angles of ribbed plates. The number and the location of ribbed plates is defined by the finite element calculations and the stress analysis of the different reinforcement structures. Buckling analysis is carried out to check the stability of the defined reinforcement structure.
