摘　　要：对板材磁流变弹性体胀形过程进行了数值模拟,比较分析了不同磁场条件下磁流变弹性体胀形过程板材速度场和应力场的分布,给出了不同磁场条件下磁流变弹性体对胀形构形的影响规律。结果表明,磁流变弹性体的剪切模量随着磁场的增加而增大,构形由椭圆形变为锥形,磁流变弹性体作为软模对板材成形性具有可调控作用,拓宽了板材软模成形的应用范围。In this paper,the numerical analysis on magnetorheological elastomers bulging for sheet metal is carried out.The velocity and stress distribution of the sheet under different magnetic intensitie s are compared and analyzed.Effect of magnetorheological elastomers on bulging configuration is given.The results show that the shear modulus of the magnetorheological elastomer increases with the increase of the magnetic field,and the configuration changes from elliptical to the conical shape.It broadens the application range of flexible-die sheet metal forming.
