Hammer Forging Process for 300M Ultra High Strength Steel Die Forging of Landing Gear Cylinder
摘要
Abstract
The material flow stress model for 300M ultra high strength steel has been established by hot compression tests on the Gleeble-1500 thermal simulation testing machine. The hammer forging forming for 300M ultra high strength steel die forging of landing gear cylinder has been investigated by DEFORM 3D FEM software, the influence of hammer forging under different process parameters has been researched in this paper. The results show that: the die forging filled completely at 1 l00℃ initial forging temperature after the three fires;the average stress of the forging is 228 MPa and the average strain is 1.51, which provides technical reference for hammer forging process.关键词
