| Abstract: | In this paper,the tension-bending test of 2024 alloy profile with high strength and thin wall thickness for aeronautics is carried out,and the principle of single variable is guaranteed.The influence of pretension between 1%and 3%on the springback deformation and fold of 2024 alloy profile under solution state is analyzed by comparing the results of several groups of tension-bending tests.The test results can be used to determine the optimum pretension for the actual production of the product. |
