航天大型薄壁回转曲面构件成形制造技术的发展与挑战

Thin-walled curved-surface components are a kind of components that are widely used for high-end carrier equipment in the aerospace industry. With the development toward large-sized, light-weight, high-performance, long-life and high-reliability of new generation aerospace vehicles, strategic missiles, and ships, it is urgent to develop manufacturing technologies for large-sized thin-walled curved-surface components. This kind of components is difficult to manufacture because of their thin thickness, large size, curvature changes, extreme size combination, light-weight and high-strength materials, and high-performance requirements. In this paper, the manufacturing technologies of aerospace large-sized thin-walled axisymmetric curved-surface components are reviewed with respect to their development history and classification. Based on the classification, the corresponding applications and latest research progress of these manufacturing technologies are reviewed. Furthermore, the process characteristics, component performances, and the development potentials of these manufacturing technologies are compared. Finally, the development trend and technical challenges of the manufacturing technology of aerospace large-sized thin-walled axisymmetric curved-surface components are summarized.
