中文摘要：

采用有限元软件Deform-3D模拟了连轧驱动等通道转角大应变技术,研究了工件的大应变过程,重点分析了模具通道夹角（分别为95°、97.5°、100°、102.5°和105°）对工件有效应变、轧制驱动轮扭矩以及大应变技术能量消耗的影响。结果表明：随着通道夹角增加,应变呈下降趋势,应变突变幅度减小,平稳性提高;各轧制轮上的扭矩减小,主动轮所占总扭矩之比减小,扭矩分配更合理;当通道夹角为100°时,工件的底部镦粗现象减小,有效应变值也达到所需值,能耗达到最小值。

英文摘要：

The finite element simulation of rolling driven equal angular channel large straining technology has been carried out by using Deform-3D software,and the large straining deformation process of workpieces is analyzed,with the special focus on the influence of channel angle（the angle is 95°、97.5°、100°、102.5° and 105°,respectively）on the effective strain,torque of rollers,and energy consumption of large straining technology.The results show that,with the increasing of channel angle,the effective strain and strain mutation amplitude decreases,but stationarity improves;as each torque of rolling wheel decreases,the ratio of driving wheel torque and total torque is reduced,but the distribution of torque becomes more reasonable;when the channel angle is 100°,the upsetting phenomenon in the bottom of workpiece decreases and the effective strain has reached the desired value,and the energy consumption has reached the minimum.
