| 摘 要： | 钢结构中特厚钢板焊接应力的理论分析一直为人们所关注。基于有限元软件ANSYS,采用高斯热源模型加热,利用生死单元,动态模拟分析80 mm特厚钢板对接焊过程中,对多层、多道焊的温度场进行加热模拟,实现焊缝的动态生成,跟踪应力场的变化情况。分析结果与重庆观音岩长江大桥构件焊接试验结果基本一致,为特厚钢板构件的设计和制作提供有实用价值的参考依据。

| Abstract: | The theoretical analysis of welding stress in extra-thick plates has been concerned.Based on ANSYS,using Gauss heat source model heating and element of birth and death,dynamic simulating is used in analysing the butt welding process of 80mm extra-thick plates.The multi-welding of heating temperature field is simulated,achieving the weld dynamic generation and tracking the changes of the stress field.Simulation results gear with Guanyinyan Yangtze River Bridge welding test results.It offers a useful referenc... |
