Abstract:

Complex thin-walled component with high ribs has wide application prospect in aerospace vehicles. Integral forming is an important technology to realize the lightweight component processing, and is also one of the engineering challenges in current manufacturing field. In integral manufacturing processes, metal spinning-additive hybrid manufacturing represents the academic frontier and development trend of the integral forming of complex thin-walled component with high ribs. In recent years, the research teams of the authors work on the spinning-additive hybrid manufacturing of complex aerospace thin-wall cylinder. This paper reviews the research status of spinning of stiffened cylinder and transformative-additive hybrid manufacturing, respectively, and systematically introduces the preliminary achievements of our teams, including the fracture mechanism and microstructure evolution of aluminum alloy stiffened cylinder during the flow spinning, the thermodynamic behavior and microstructure control during additive manufacturing based on the inner wall of spun cylinder, and spinning-additive hybrid manufacturing process; and prospects the development of spinning-additive hybrid manufacturing as well. Furthermore, this paper presents the technology status and trend of the hybrid manufacturing of complex thin-walled cylinder with high ribs, which provides a guide for developing integral forming technology of complex thin-walled components.

Key words: aluminum alloy, thin-walled component, metal spinning, additive manufacturing, hybrid manufacturing
