摘　　要：基于Deform 3D平台,对钛合金大型框锻件等温成形过程进行了数值模拟,分析研究了变形工艺参数(变形温度、变形速度及摩擦)对变形均匀性的影响。引入变形均匀性参数对变形均匀性进行分析,结果表明:变形工艺参数对TC4钛合金大型框锻件等温成形过程具有显著影响,在锻件成形过程中应适当增加变形温度、降低加载速度和保持良好的润滑条件,以期提高坯料变形的均匀性。On the basis of Deform 3D platform,the numerical simulation has been conducted to large-sized frame forging of Ti-alloy.The influence of deformation process parameters including deformation temperature,speed and friction to deformation uniformity has been analyzed.Deformation uniformity index has been introduced to analyze the uniformity.The results show that process parameters have significant influence on the forming property of frame forging.Higher deformation temperature,lower loading speed and good lubrication condition can improve the uniformity of blank deformation.
