摘要:
基于商用有限元软件ANSYS的APDL语言,选用适用于CO。气体保护焊的双椭球热源模型,建立Q345B厚板T型接头多层多道焊的有限元模型,采用单元生死技术,通过编制子程序逐层逐段地激活焊缝单元来模拟焊缝材料的填充过程,得到不同焊接速度下模型温度场的分布情况以及模型典型位置的热循环曲线,并通过实验验证了仿真结果,证明了焊接模拟的可靠性,为实际焊接过程分析提供一定的理论帮助.
Abstract:
Based on the APDL( ANSYS Parametric Design Language ) of commercial finite element softwareANSYs and selecting the double-ellipsoid heat source model,the finite element model of (345B plate T-jointmulti-layer and multi-pass welding is created. With the element birth and death technology and simulating thefilling process of weld material by programming subroutine which activates the welding element step by step.The temperature field distribution regularities of the model under different welding speeds are analylized andworked out the thermal cycling curves of typical positions.The simulation results are verified through experi-ment which prove the reliability of the welding simulation and provide some theoretical help to analysis the ac-tual welding process.
