Abstract:

 In order to explore the feasibility of magnesium alloy integral panel bending and the law of metal flow in the bending process of magnesium alloy panel, the bending of AZ31 magnesium alloy grid panel was numerically simulated and experimentally studied. Then, the geometric model of finite element numerical simulation was established, the bending process of AZ31 magnesium alloy grid panel was simulated by finite element software, and the distributions of temperature field, strain field, stress field and failure coefficient in the bending of magnesium alloy grid panel were analyzed. Furthermore, the appropriate process parameters of AZ31 magnesium alloy panel were determined, the experimental research of bending for magnesium alloy grid panel was carried out, and the qualified bending parts of magnesium alloy grid panel were obtained. Finally, the dimensional accuracy of forming parts for magnesium alloy grid panel was analyzed, and the simulation results were in good agreement with the experimental results with the maximum relative error of 16.7%.
