摘　　要：为了解决高速冷滚打成形零件质量缺陷问题,进行了冷滚打成形过程热力耦合模拟,得到了工件应力场和温度场的分布规律。研究结果表明:随着滚打轮的打入,工件成形区的温度急剧升高,工件温度较高的区域分布在工件的剧烈变形和金属流动较大的区域。To solve the parts quality defects of high-speed cold rolling,the cold rolling deformation process was simulated by using thermal-mechanical coupled finite element method. The variational rules of stress and temperature were obtained. The results show that the temperature of the workpiece forming area is increased rapidly with the roller beating into the workpiece. The higher temperature region is in the severe deformation and larger metal flow areas of the workpiece.
