The Research of High Internal Pressure Forming Process of Variable Cross-Section Elliptical Tube

Abstract:

Based on the ETA/DYNAFORM elastic-plastic explicit finite element platform, the finite element model of high internal pressure forming was established and the forming process was simulated. Through simulating, the forming process was researched. The distribution law of wall thickness, stress and strain was revealed in forming process. The results show that: the thinnest wall lies in the middle of forming part, and the thickest wall in the end of feeding areas. Both maximum equivalent stress and minimum equivalent strain lie in the forming fillet of the large elliptical cross-section. These play an important guiding significance on molding process.
