Title Finite Element Analysis And Process Research Of Magnesium Alloy Triangular Box Deep Drawing.
Abstract
Deep drawing is a typical method of processing open thin-walled hollow parts, and it plays an important role in the actual production of stamping. The cracking and wrinkling is the most serious phenomenon in the process of stamping of triangular box, and it is the most prone to defects. The surface quality of the parts can be improved and the cracking and wrinkling defects can be controlled by finite element simulation analysis of the triangular box deep drawing.
In this paper, the background and significance of the triangular box deep drawing ware given, the main features of the rectangular box drawing deformation ware analyzed, and the major defects of the triangular box deep drawing ware researched.First of all, the stamping mould was modeled by solidworks. Then Simulation analysis of deep drawing was simulated by finite element analysis software Dynaform .The influence of BHF, mould parameters and sheet parameters and other factors on the triangular box deep drawing was analyzed, The orthogonal test and parameter analysis was proposed, and the optimal parameters combination was found, which laid the foundation of discussion the stamping process of asymmetrical complex rectangular box.
Keywords Triangular box deep drawing Univariate analysis Orthogonal Test
