摘　　要：利用DEFORM-3D,采用刚粘塑性有限元法,建立了带阻尼台叶片精锻过程的三维有限元模型,模拟分析了上模压下速度对带阻尼台叶片精锻过程的影响规律.获得了不同上模压下速度时的等效应力、最大主应力等场变量分布及带阻尼台叶片精锻过程载荷-行程曲线,并根据最大主应力分布提出了对终锻坯料形状设计的建议.研究结果对带阻尼台叶片精锻工艺的制订具有重要的指导意义.Based on the platform of DEFORM -3D, 3D FE model of precision forging process of the blade with a damper platform has been built by rigid-viscoplastic FEM. The influence laws of upper die velocity on precision forging process of the blade with a damper platform were simulated and analyzed. And the distribution of effective stress field, maximum principal stress field and curves of load vs. displacement were ob- tained. A suggestion for the shape design of final forging was proposed according to the maximum princi stress field. The obtained results provide a significant basis for determining technological parameters of blade forging process.
