摘要：

铝合金异形截面环件是航天航空和国防装备的重要结构件，铝合金异形截面环件目前多采用自由锻成形或者

简化为矩形截面环件后轧制成形，使环件生产周期长、材料利用率低、环件的组织性能差，严重限制了该类

环件的应用和发展。针对2A14铝合金锥面筒形环件进行了轧制过程数值模拟和实验研究，提出了形状相似环

件毛坯设计方法和锥形环件轧制过程的合理工艺参数范围计算方法，并基于ABAQUS/Explicit平台建立该环

件轧制过程的三维热力耦合有限元模型。通过分析毛坯结构对成形环件尺寸误差和变形均匀性的影响，得到

了等截面积环件毛坯成形尺寸误差最小的结果。并根据模拟结果进行轧制实验验证，成功轧制出合格的锥面

筒形环件。

Aluminum alloy profiled ring is an important structural part for aerospace and national

defense equipment. Nowadays aluminum profiled ring is usually formed by free forging or by

rolling forming simplified as rectangle section ring. So the ring production cycle is too long

with low material utilization rate, poor ring organization performance, which severely

restricts the application and development of this ring. The rolling process of aluminum alloy

2A14 cone cylinder ring was numerically simulated and researched by experiments, and the

similar shape forging blank design method and the taper ring rolling process calculation

method of the reasonable process parameters were put forward. Then, based on ABAQUS/Explicit

platform, the three dimensional coupled thermo-mechanical finite element model for the ring

rolling process was established. And by analyzing the influence of the blank structure on the

dimension error and the deformation uniformity of the formed ring, the minimum size error of

equal section area blank was obtained. Furthermore, the simulation result was verified by

experiment of rolling, and the qualified tapered cylindrical ring was rolled out successfully.
