Abstract

Abstract

Thin-walled titanium alloy rings are critical aerospace components, whose machining deformation severely restricts their dimensional accuracy and service reliability. A full-process finite element model covering rolling, cooling, heating, bulging and heat treatment was established for rectangular thin-walled titanium alloy rings, to systematically investigate residual stress evolution during forming and its effect on machining deformation. The regulation mechanism of bulging on the stress field was revealed by analyzing stress distribution under different bulging parameters, and a theoretical model correlating residual stress and machining deformation was constructed and verified via simulation and experiments. Results show that residual stress mainly originates from the initial cooling stage, and subsequent bulging and heat treatment can significantly reduce stress amplitude and improve distribution uniformity. The optimal residual stress state is achieved at a bulging ratio of 4% and a bulging temperature of 800 °C. Simulation results are in good agreement with theoretical calculations, with a maximum error of 20.37%. The optimized process and model were validated effective for special-shaped rings, providing a theoretical basis and process guidance for residual stress regulation and deformation control of titanium alloy thin-walled rings.
