Review of integral forming methods of different structural ribs of cylinders
Thin-walled cylinders with ribs are important load-bearing components in the aerospace field.The plastic integrated manufac-turing can efficiently form the thin-walled cylinders with ribs and complete metal streamline,which is an important means to realize the lightweight of aerospace equipment and the improvement of its performance.Aiming at the stiffener structure of thin-walled cylinders with ribs,the integral forming methods of thin-walled cylinders with single rib,thin-walled cylinders with cross ribs,and thin-walled cylinders with helical ribs were reviewed from three perspectives:processing theories,material forming laws,and process parameters optimization.In addition,the forming parameters and characteristics of ribs with different structures under different processing methods were compared.The advantages and limitations of various integral forming methods were summarized.The development trend of integral forming methods for thin-walled cylinders with ribs was reviewed,and the prospect of forming higher,fuller and more uniform reinforcing ribs was presented.
