摘要

为提高轻质航空管材的成形质量，研究了不同管材规格、成形要求和工艺参数对大直径薄壁（LDTW）LF2M 铝合金管材（AAT）弯曲成形的影响。建立并验证了 LDTW AAT 弯曲的有限元分析模型。结果表明，随着心轴延伸长度 em 的增加，薄壁率呈上升趋势。随着 em 的增加，整体壁厚比减小。随着 em 的增加，椭圆度先减后增。弯曲半径对壁厚变化有很大影响。这对指导轻质 LDTW 铝合金航空管的弯曲成形具有重要意义。

Bending forming of lightweight large diameter thin-walled aluminum alloy aviation tube

To improve the forming quality of lightweight aviation tubes, the influence of different tube specifications, forming requirements and process parameters on bending forming of large diameter thin-walled (LDTW) LF2M aluminum alloy tubes (AATs) was studied. A finite element analysis model for LDTW AAT bending was established and verified. The results show that with the increase of mandrel extension length $e_{m}$ , the wall-thinning ratio tends to increase. With the increase of $e_{m}$ , the overall wall-thickening ratio decreases. With the increase of $e_{m}$ , the ovality decreases first and then increases. The bending radius has a great influence on wall thickness variation. It has great significance to guide the bending forming of lightweight LDTW aluminum alloy aviation tube.
