In this paper, the stress and strain distribution, tube wall thinning and the cross section ovalization in Aluminum alloy thin-walled tube NC bending with small bending radius have been investigated through experimental method combined with finite element method and theoretical analysis.

本文采用实验法，并结合有限元模拟和理论解析法，研究了与铝合金薄壁管小弯曲半径数控弯曲成形质量密切相关的应力应变分布、壁厚变化和截面畸变等关键问题。

The effects of some parameters, such as mandrel ball numbers, mandrel extension length, bending angle, lubrication condition of pressure die, relative bending radius and material, on ovalization have been investigated by experimental method, and the effective methods to reduce the ovalization are proposed.

文章采用实验法，研究了芯头个数、芯棒伸出量、弯曲角度、压块润滑状态、相对弯曲半径、材料等因素对截面畸变的影响；并提出了减小截面畸变的有效措施。

The results show that increasing the ball numbers and mandrel extension length may reduce the ovalization, but leads to more remarkable wall thinning; the ovalization becomes more severe with the larger bending angle; the smaller the relative bending radius, the larger the ovalization is; the ovalization and wall thinning degrees are both smaller in the case of pressure die with dry lubricant; and under the same bending condition, the ovalization of LF2M tube is larger than the one of 1Cr18Ni9Ti tube.

结果表明，增加芯头个数与芯棒伸长量都能减小弯管的截面畸变，但两者都导致弯管壁厚减薄量增大；随着弯曲角度的增加，截面畸变越严重，相对弯曲半径越小，无芯棒与芯头支撑段弯管的截面畸变愈严重；在压块无润滑情况下，弯管的截面畸变和壁厚减薄量都小，并且在同等弯曲条件下，1Cr18Ni9Ti弯管的截面畸变小于LF2M弯管。
