| 摘 要： | 根据在Gleeble-1500热模拟试验机上得到的数据,在Marc软件中建立了2124铝合金的数据库;采用二维弹塑性大变形有限元法,对该铝合金超厚板热轧过程进行了数值模拟,分析了热轧过程中轧件温度场的分布和变化规律.结果表明:在整个轧制过程中,轧件内部节点的温度变化缓慢,而表面节点的温度变化较为剧烈;模拟计算的出口处板坯表面温度(431℃)与实测的表面温度(436℃)吻合较好.

| Abstract: | Based on the results of the thermal simulation test on Gleeble-1500,the material database of 2124 aluminum alloy was developed and used in Marc finite element software.The temperature field distribution and changing discipline of the 2124 aluminum alloy plate in the whole hot rolling process were studied with the aid of two dimensional elastic-plastic and large deformation finite element method,using general software Marc.The results indicated that the plate surface temperature changed sharply during the ro... |
