摘　　要：利用Deform软件对长轴类T形截面锻件自由锻成形过程进行了有限元分析,对成形模具结构进行了优化并对成形过程中可能出现的缺陷进行了预测和分析。根据模拟结果,增大下模长度可显著增加成形过程中金属沿锻件轴向流动的摩擦阻力,从而提高锻件两侧凸耳的填充效果。The finite element analysis is performed on free forging process of long shaft forgings with T-shape section. The forming moulds are optimized and the possible defects in forming process are predicted and analyzed too.According to the simulation results,increasing the length of the lower mould can significant increases the axial flowing frictional resistance of metal in the forming process,thus improving the filling effect of the lugs of two sides of forging.
