金属带材拉伸弯曲矫直过程简化解析分析之二─—理想弹塑性带材在第1个弯曲辊上的拉弯过程分析

Theoretical Investigation into Continuous Tension Leveling Process of Metal Strip (2) --Analysis on the tension leveling process of elastic-perfect plastic metal strip over the first bending roll

对理想弹塑性金属带材在第１个弯曲辊上的拉伸弯曲过程进行了详细的分析，给出了不同应力分布形式的边界条件、带材产生塑性延伸的条件、带材塑性延伸率的计算公式，从而确定了带材延伸率与带材张力和带材弯曲曲率之间的关系．

The tension leveling process of the elastic-perfect plastic metal strip on the first bending roll is investigated. The conditions to form different patterns of stress distribution, the conditions to allow the metal strip Undergo plastic elongation, the calculation formula of the plastic elongation and the relationship among the elongation, tension and bending curvature or radius are discussed and clearly expressed.
