Deformation Pattern of the Large Generator’s Retaining Ring during Hydraulic Bulging Strengthening

摘要：

In accordance with hydraulic bulging strengthening technology for large generator retaining rings (Mn18Cr18N), the bulging deformation process of retaining rings is simulated by MARC software. The key factors such as the punch taper angle and contact pressure are analyzed which influence on the deformation.It has been proofed for carbon steels with small ratio mould. It is observed that adjusting the punch taper angle and controlling the contact pressure theoretically can make the rings deforming uniformly during the hydraulic bulging strengthening processes, and these results provided the credible theoretical bases of technology application.
