Abstract
This invention relates to a manufacturing method for a lightweight, high-load-bearing, complex integral thin-shell, belonging to the field of advanced manufacturing. It solves the problem that existing methods struggle to efficiently, cost-effectively, and precisely manufacture such shells. The manufacturing method includes the following steps: S1, establishing a theoretical model of the thin-shell; S2, performing finite element simulation of subsequent assembly processes to obtain a reconstructed model; S3, designing a manufacturing process scheme based on the reconstructed and theoretical models, including a thin-shell forming scheme and a preform manufacturing process scheme; and S4, manufacturing the thin-shell according to the manufacturing process scheme. This invention, through multiple key steps such as thin-shell reconstruction, thin-shell forming scheme design, and preform manufacturing process scheme design, effectively improves the precision and efficiency of thin-shell manufacturing, achieves precise weight control, enhances the load-bearing capacity of the thin-shell, shortens the processing cycle, and reduces costs.
