摘要
本文按材料的幂强化模型推导了工程中板材塑性弯卷时弯板力矩的计算公式。用该公式计算了三种不同工况下试验筒体的弯板力矩值,并与实测值进行了比较。比较结果表明,本文所提出的公式比目前工程界采用的由德国、苏联及美国推荐的弯板力矩公式有较高的精度,并具有一定的实用性及通用性。
In this paper, the calculating formula of bending moment plastically rolling plates was developed for power-hardening materials. It was applied to compare with three tube specimens subjected to different loading conditions.It is evident that this formula is more exact than those proposed by German, Russian and American. Therfore, it seems to be valuable.
