| 摘 要： | 由带极埋弧堆焊原理及GoldaK(热源模型理论设计了带极埋弧堆焊有限元热源模型,基于有限元软件MSC.MARC平台,编写FORTRAN子程序来实现移动热源的加载,并采用了MARC软件对厚板带极埋弧堆焊温度场进行了数值模拟,同时对焊缝形貌及试验测得的热循环曲线进行验证,得到了与试验结果较吻合的温度场计算结果.结果表明,提出的热源模型适合带极埋弧堆焊过程数值模拟.

| Abstract: | A thermal source for submerged arc overlaying is designed based on its principle and heat source model of Goldak, and a fortran subroutine is compiled to implement the translation of thermal source in the FEA software MSC.MARC. Finite element simulation of temperature field of submerged arc strip overlaying on thick plate was established. The simulation results are in good accordance with the actual thermal cycle curve, which proved the model is correct. |
