高性能计算平台在铜铁薄板热轧复合数值模拟中的应用

Numerical Simulation of Cu/Fe/Cu Thin Plate Hot-roll Bonding Based on the Platform of High Performance Computation

基于高性能计算平台,利用ABAQUS有限元软件首次对Cu/Fe/Cu薄板进行了热轧复合模拟。应用高性能计算平台不仅大大地提高了计算效率,而且还提高了计算精度。通过模拟仿真,获得了轧制复合过程的应力应变场和温度场变化,对热轧过程有更清晰的认识;通过与实验对比,数值模拟与实验结果吻合良好,复合板各层厚度变化误差在5%左右,可对原始板料的厚度提供参考,同时对工艺的制定提供良好的理论指导。

With the help of finite element method software ABAQUS, numerical simulanon of the copper/ steel/copper thin plate hot-roll bonding has been carried out based on the platform of high performance computation （HPC）. It could improve the compute efficient dramatically and increase the compute precision with the aid of HPC. The stress and strain field and also the temperature field were obtained by simulation during the rolling process which bring us a more clearly understand about the hot rolling process; the simulation result are well agree with experiment through contrast between simulation and experiment, the error of the variation in thickness of each layer are 5%, which could provide a reference for initial thickness of the thin plate and also provide a good theoretical conduct at the same time.
