| 摘 要： | 钢管-板节点连接是大跨越输电钢管塔常用的连接方式,焊接残余应力是影响节点受力的主要因素。基于ANSYS的焊接模拟方法,采用生死单元技术,对节点的温度场和应力场进行数值模拟,分析了钢管-板连接节点的焊接残余应力对极限承载力的影响。结果显示,焊接残余应力在焊缝区及其附近最大,是导致焊缝断裂的主要原因。 |

| Abstract: | Steel tube - plate connected joint is commonly used in large crossing transmission steel tower, the welding residual stress is the main factors affecting the joint. Based on welding simulation method of ANSYS, using the life and death of nodes element technique, the temperature field and stress field at the nodes are numerically simulated, the effect of the residual stress and deformation to ultimate bearing capacity is analysed. The results show that welding residual stress in the weld zone and its vicinity is the largest, so it is the main cause of weld fracture. |
| Keywords: | transmission tower steel tube-plate connected joint welding residual stress |
