摘要
此文利用主应力法推导出圆管空拔壁厚变化量解析式。该式计算结果与以定常三维流动上界解析同类问题结果相接近,且表达式简单,也与拔管的实验结果相一致。因而,可在圆管空拔壁厚计算时推广应用。
A formula for calculating Variation of wall thickness during tube sinking was obtained by means of slab method. The results of formula (22) is similar to that of formula (23) ,and the formula (22) is more simple than formula (23) and is mor approximate the result of experiment. so the formula (22) can be applied to calculating variation of wall thickness during tube sinking.
