| 摘 要： | 球罐容积大、壳体壁厚、球壳板刚度较大,在组装过程中不可避免地产生较大的组装与焊接残余应力和变形,因而球罐焊后整体热处理对其安全使用尤为重要。本文采用SYSWELD工程有限元分析软件中的热处理工具,结合实际的热处理规范要求,加载焊接后模型的温度场和残余应力场状态,以达到对焊后热处理的真实模拟。为研究焊后热处理工艺对减小焊接残余应力的意义提供理论指导。

| Abstract: | Spherical tanks have the features of Large tank volume,shell thickness,shell plate stiffness,it will inevitably produce a larger assembly and welding residual stress and deformation in the assembly process,and thus the overall heat treatment after welding tank using is particularly important to safety.In this paper,SYSWELD heat treatment tool engineering in the finite element analysis software combining with the actual heat treatment specifications,the model of welding temperature field and residual stress ... |
