文章推荐了空拉管壁厚计算中由A_o求S_H的算图和由A_H求S_o的算图,对它们的准确程度作了分析。由A_H求S_o的算图对组织负偏差壁厚管材的生产,很有用。
In this paper, we propose the calculation of S_H by A_o and the calculation of S_o by A_H in the calculation of wall thickness of hollow tube, and analyze the accuracy of them. The calculation of S_o by A_H is useful for the production of tissue negative wall thickness pipe.
