【摘要】 在大型商业有限元软件平台上 ,开发了板带轧制三维模拟系统 ,讨论了改变前、后张力时 ,轧件的三维变形特点。模拟结果显示 :增加张力限制金属横向流动 ,加大厚向变形 ,使断面厚度更加均匀 ,其中同时改变前后张力对变形的影响效果最大。更多还原

【Abstract】 A simulation system of cold strip rolling has been developed on the bases of a large commercial FEM software Variation of three dimensional deformation of strip under different forth and back tension can be obtained The results show that enhanced tension restricts lateral flow,enhances deformation in thickness direction,makes outgo thickness more uniform The influence is the largest when changing forth and back tension simultaneously更多还原
