摘要:
为了研究轴向荷载下承插搭接焊钢管接头的应力分布规律和应力集中现象,根据焊接类型和角焊缝型式的不同组合,采用有限元软件ANSYS建立了9种接头计算模型,开展应力分析工作。分析结果显示,轴向荷载作用下,凸角焊缝虽增加了焊材用量和焊接工作量,但结构受力最好,平角次之,凹角焊缝虽节省焊材,但结构受力最差。研究表明,相同荷载作用下,内外双焊接头应力最小,可利用搭接区钢材分担受力,但焊接工作量最大;外焊接头整体应力分布较为均匀,但焊接在管外留槽施工,较为不便;内焊接头处管壁应力分布不均匀,内焊缝和承口扩径段管壁应力最高,但焊接可以在管内施工,较为方便,可以优先考虑使用。
Abstract:
In order to study the stress distribution and stress concentration of socket lap welding joints for buried steel pipes under axial loading, nine joint calculation models are established by using the finite element software ANSYS according to different combinations of welding types and fillet weld types. The analysis results show that under axial loading, although the convex fillet weld increases the amount of welding materials and workload, the structure has the best stress performance, followed by the flat angle. Although the concave fillet weld saves welding materials, the stress performance of the structure is the worst. The research shows that under the same load, the stress of inner and outer double welded joints is the smallest, and the overlapping area can share the stress, but the welding workload is the largest. The overall stress distribution of the external welded joint is relatively uniform, but the weld at the outside of pipes is inconvenient. The stress distribution at the inside welded joint is uneven, and the highest stress appears at the inside weld and socket expanding section, but the welding can be constructed inside the pipe, which is more convenient and can be used preferentially.
