摘要: 应用三维大变形弹塑性有限元法,对方矩形管连续辊弯成形过程中金属流动规律以及应力分布进行了模拟分析。考虑了各道次之间的数据信息传递,保证了下一道次变形历史的延续,从而真实模拟了方矩形连续辊弯成形过程。获得的结果对连续辊弯成形中的产品质量的控制和孔型的优化有着重要意义。

Abstract: A simulation analyses of metal flow ruler and stress distributions of square rectangle tube in continue roll-forming process by using 3D big deformation elastic plastic finite of element method is presented. Transmit data information is considered inter each pass, and then square rectangle tube in continue roll forming process is real simulated. The simulation results are useful for product quality and the profile designed in continue roll forming.

Key words: Deformation, Elastic plastic finite clement, Square rectangle, Stress field
