摘要
通过对有限元软件ANSYS的二次开发实现对双丝埋弧焊焊接温度场的有限元分析.利用APDL语言编写了移动热源的热流计算和加载程序,特别是使用高效的矢量运算和数组存储简化了计算加载的操作,实现了双丝焊移动热载荷的准确顺序加载这一大创新点.通过实例计算表明对热流计算与加载过程的这种改进,缩短模拟计算时间、减少计算量、提高计算效率,验证了此算法正确可行,此种热场算法可以很方便的由双丝焊的热场计算与加载推广到多丝焊热场的计算与加载.
The temperature field of the twin-wire submerged arc welding was analyzed by finite element software ANSYS of secondary development.The calculation and loading of heat of mobile heat source were programmed by ANSYS parametric design language.In particular,by the use of vector,the calculation and loading operation were simplified and the efficiency of simulation was improved.The experiments verify that the algorithm of heat load makes simulation time and calculation reduce,and the algorithm is feasible and efficient.This algorithm can be applied to the thermal calculation and loading of temperature field for multiple wire welding.
