FE Simulation and Test for the Deformation of Tubes’ Different Cross-Sections[J]. Aeronautical Manufacturing Technology, 2008, 51(22): 91-93. DOI: 10.16080/j.issn1671-833x.2008.22.003.
FE Simulation and Test for the Deformation of Tubes’ Different Cross-Sections
the simulation analysis and test verification on the tubes’ cross ̄section deformation are carried out. It is pointed out that the change of tubes’ larger cross-section occurs nearby bending center corner and the change of smaller one takes place in tubes’ tangent segment. After the finite element calculation
there is large deviation in change-ratio of long axis on the cross-section
actual the reason is caused by the error of the match between tubes and dies.
