摘要
Abstract
Presents the simulation and analysis of the rotary forging of a disc using a finite element method, which re
veals the thinning at the disc center is caused by higher radial and tangential tensile stresses resulting from the local
loading of a rotary die and acting at the center of a workpiece, and proposes a new design of rotary die with a hole
opened in its center to prevent the continuous occurrence of shortening in the axial direction and elongation in the tan
gential and radial directions, and concludes from simulation results that the rotary die with a hole opened in its center
is effective for prevention of thinning or cracking at the center of a disc during rotary forging.关键词
