铜、铁、铜叠片热轧复合的数值模拟

Numerical Simulation of Cu/Fe/Cu Thin Plate Hot-Roll Bonding

利用ABAQUS有限元软件对Cu、Fe、Cu叠片进行了轧制复合热力耦合模拟。获得了轧制复合过程的应力-应变场和温度场变化,对热轧过程有了更清晰的认识;数值模拟与试验结果吻合良好,复合板各层厚度变化误差在5%左右,可对预测产品厚度,同时对工艺的制定提供理论指导。

With the help of finite element method software ABAQUS, coupled thermal-stress simulation of the cop- per/steel/copper thin plate hot-roll bonding was investigated. The stress and strain field and the temperature field, which was helpful to understand the hot rolling process, were obtained during the rolling process. The simula- tion results well meet with experiment through simulations and experiments, and the error of the variation in thick- ness of each layer is about 5 %, which can provide a prediction for the thickness of the production and also can pro- vide a good theoretical conduct.
