T型接头焊接温度场ANSYS仿真分析

1、焊缝凝固过程的温度场分析初始条件：焊接件的初始温度为 25度，焊缝温度为3000;对流边界条件：表面传热系数为 5e-4，比热容0.2，材料密度0.28，空气温度为25度; 求2000s后整个焊接件的温度分布1、选择网格单元类型PreprocessorEleme nt TypeAdd/Edit/DeleteAddThermal MassSolidBrick 8 node:JLHE DtF lltli70.UT 05msumjibI qtftr|POtfKGfOoEfinBii Elgnrant Tvn曲：观逼舱LX皿-Prdf er ErLceBZJ Ftnpro弗。暫库 ors E j 日g
