The machining deformation of a large pressure cylindrical shell might affect its subsequent machining accuracy and application requirements. A large titanium alloy pressure cylindrical shell after deformation was studied in this paper. Based on the thermal elastic-plastic and creep finite element theory, the numerical simulation of thermal correction of the deformation correction process of the cylindrical shell was carried out through the calibration tooling and thermal correction method. The results show that the error of elliptic end calibration of the deformed large titanium alloy pressure cylindrical shell is controlled within 1%, which could meet the engineering requirements. The overall calibration effect achieved with the calibration tooling of ring-shaped is better, and the error is reduced by 0.2% compared to the calibration tooling of cross-shaped. The holding time, heating rate and cooling rate of heat treatment have little effect on the calibration effect of the deformed cylindrical shell, while the spring stiffness has a great influence. Finally, a set of good heat treatment straightening process for large pressure cylindrical shell was obtained.
