Abstract：

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.
