| 摘 要： | 利用Deform应用软件,对美国标准AISI-1008钢圆柱形坯料和凹形坯料镦粗过程进行数值模拟,从等效应变和流线两个方面进行了对比分析,分析结果表明:当高径比为1.5时,凹形坯料的鼓肚现象明显得到改善,并且等效应变代数值有所减小,内部变形的均匀性明显提高.

| Abstract: | With Deform application software the cold upsetting processes of cylinder and concave blank of American Standard AISI-1008 steel are simulated,the comparison analysis is done from two fields: equivalent strain and flow curve.It is showed from the analysis that while h/w ratio is 1.5 the bulging of concave blank is improved obviously,algebraic value of equivalent strain gets smaller and uniformity of inner deformation improved. |
