碟形封头冷旋压成形时的数值分析及旋压力计算

Numerical Simulation & Force Calculation of Disc-Shape End Deformation in Spinning

建立了碟形封头冷旋压的三维有限元数学模型 ,分析了封头在冷旋压成形过程中应力应变的分布规律 ,计算了旋压力并分析了其变化的原因 ,为更有效地进行旋压加工前的科学预测。

The 3D FEM analysis model of disc shape ends is established. The law of stress and strain distribution law in the deformation zone of end spinning is analyzed. The deformation force is calculated and its variety reason is analyzed. It provides reliable methods and foundation for scientific fore casting deformation law and optimizing process before the end part is machined, and further numerical controlling of disc shape end spinning.
