超大口径药形罩强力旋压应力应变场有限元分析

摘要

药型罩应力应变场的分布规律分析是研究其成形机理的基础和前提.基于ABAQUA/Explicit平台建立超大口径药型罩强力旋压三维有限元模型,通过数值模拟对药型罩强力旋压成形过程应力应变场的分布规律进行了分析,研究表明,药型罩的圆角处和接触区应力值较大,在强力旋压过程中该区域容易破裂,实际生产中应予以关注.%Distribution of Liner stress and strain field analysis is to study the forming mechanism of the basis and prem-ise. Based ABAQUA/Explicit platform to build large diameter Liner Power Spinning dimensional finite element model, the process of distribution of stress and strain fields through numerical simulation Liner power spinning analyzes,studies show Liner round corner and the contact stress area is large,in the process of power spinning the region prone to rup-ture,the actual production should be concerned.
