Based on the bulging principle of different ellipticity dies, the methyl vinyl silicone rubber with excellent thermal stability and heat transfer performance was chosen as the viscous medium. The finite element analysis and experiments of viscous warm pressure bulging (VWPB) of AZ31B magnesium alloy were conducted to analyze the influence of different ellipticity dies on the formability of AZ31B magnesium alloy. At the same time, based on the grid strain rule, the forming limit diagram (FLD) of VWPB of AZ31B magnesium alloy was obtained through measuring the strain of bulging specimens. The results showed that at the temperature range of viscous medium thermal stability, the viscous medium can fit the geometry variation of sheet and generate non-uniform pressure field, and as the die ellipticity increases, the difference value of non-uniform pressure reduces. Meanwhile, according to the FLD, the relationship between part complexity and ultimate deformation was investigated. |

基于不同椭圆度凹模胀形原理,选择具有良好热稳定性和导热性能的甲基乙烯基硅橡胶作为黏性介质,进行AZ31B镁合金黏性介质温热胀形试验,并采用有限元分析软件ANSYS/LS-DYNA对成形过程进行分析。确定AZ31B镁合金黏性介质温热胀形最佳温度,以及凹模椭圆度对AZ31B镁合金黏性介质温热胀形变形规律的影响。同时根据网格应变原理,通过对不同椭圆度极限胀形试件的测量,绘制出AZ31B镁合金黏性介质温热成形极限图(FLD)。研究结果表明,在耐热温度范围内,热态黏性介质能够适应试件几何形状的变化建立非均匀压力场,非均匀压力差值随着椭圆度的增大而减小,根据极限胀形试验绘制出的成形极限图,能够综合反映出零件复杂程度与极限变形程度的关系。 |
