Abstract：

In order to improve the filling accuracy for the sectional profile ring during the rolling process of aviation stepped-section profile ring, a ring blank design method based on the segmentation for the sectional shape features of ring was proposed, and the calculation method and correction scheme of geometric sizes in the design process of rolling ring blank were given by the theoretical analysis. Then, the rolling process of stepped-section profile ring was analyzed by finite element simulation software ABAQUS, and the simulation results shows that the rolling ring blank based on the segmentation design for the sectional shape feature of ring has a good filling effect. Furthermore, the flow law of metal in the of rolling stepped-section profile ring was revealed by numerical simulation results, and the evolution law of the geometric sizes in the of rolling of stepped-section profile ring was clarified. In addition, the rolling experiment was carried out. The results show that the sectional profile of the corresponding stepped-section profile ring can be accurately formed by the ring blank design method, and the maximum size relative error is not more than 0.72%.
