根据实验结果,作者发现了在H型件轧边端孔型中的张力饱和现象。研究了产生该现象的原因并推导了饱和张力值计算公式。计算结果同实测结果的比较表明,本文公式计算饱和张力值的精度满足工程计算的要求。 According to the experimental results, the authors found the phenomenon of tension saturation in the H-shaped side-pass hole pattern. The reason of this phenomenon was studied and the formula of saturated tension was deduced. Comparing the calculated result with the measured result shows that the accuracy of calculating the saturated tension value in this paper satisfies the requirements of engineering calculation.
