采用弹塑性大变形有限元法对板带轧制过程中变形区内摩擦力的分布进行模拟 ,分析了不同轧制工况下各种影响因素对摩擦力分布的影响 ,从而确定出摩擦力大小、中性点位置、以及接触弧长和前后滑区长度随各种因素的变化情况。
The distribution of friction in the deformation zone during the strip rolling process was simulated by the elasto-plastic large deformation finite element method. The influence of various influencing factors on the friction distribution under different rolling conditions was analyzed to determine the friction , The position of the neutral point, and the variation of contact arc length and length of the front and rear sliding zones with various factors.
