To meet the demands of precise manufacturing of high-performance complex-section rings in the aerospace field, a forward design and optimization method for the intermediate ring billet in the rolling process of TC4 titanium alloy C-section profiled rings was proposed, based on integration of flow-strain-temperature fields. Grounded in the theoretical competition behavior between diameter expansion and cross-sectional profile forming during ring rolling, the dimensional constraints for the intermediate billet that ensure complete crosssectional filling(corresponding to the flow field) were deduced forward. Subsequently, key geometric parameters influencing the ring billet volume distribution were taken as design variables, and the uniformity of strain and temperature distribution in the ring after rolling was set as collaborative optimization objectives, thereby a synergistic design process integrating forward design and intelligent optimization was established. The results demonstrate that the established system— “flow field analytical constraints, coupled with strain~/temperature field surrogate models and multi-objective intelligent optimization” —can obtain an optimal intermediate billet that simultaneously enhances the uniformity of both strain and temperature fields under the condition of complete cross-sectional filling.
