本文基于大型有限元分析软件SYSWELD,采用双椭球三维热源对JB800钢平板堆焊的温度场进行了数值模拟。结果表明,冷却时间t的计算结果与实测结果基本吻合,验证了本文所建模型的可靠性。8/5
Based on the large-scale finite element analysis software SYSWELD, the dual-ellipsoid three-dimensional heat source is used to simulate the temperature field of JB800 steel plate surfacing. The results show that the calculated cooling time t is basically consistent with the measured results, which verifies the reliability of the model. 8/5
