【摘要】 利用有限元软件为塑料薄板双向拉伸成形过程建立了有限元计算模型 ,并进行了计算和分析 ,将原用于结构计算的有限元软件引用于薄膜成形工艺领域。文中深入研究了从管坯到薄膜吹胀成型过程中的厚度分布变化和半径分布变化 ,并给出了结论。更多还原

【Abstract】 A FEM calculate model is made for initial plastic panel stretching formation,then calculating and analyzing it with the help of FEM software.Try to extent the FEM method from structure to film formation.In this paper,deeply research was made from tube semifinished product to bubble which is about distribute of radius and thick,and draw own conclusion.更多还原
