摘　　要：对带凸台的大型饼类锻件,可采用漏盘镦挤工艺进行生产。针对该工艺,利用ANSYS的APDL语言建立了镦挤过程的参数化有限元模型,采用0阶优化法,对该工艺进行了优化分析,对漏盘结构参数和变形后的坯料尺寸进行了定量分析,为确定漏盘镦挤工艺参数提供了有益的指导。For a heavy forging with bulge, the upsetting-extruding process can be adopted. The parametrical FEM model of the upsetting-extruding process is built up with APDL language of the software ANSYS. Zero-order optimization method is adopted to conduct the optimization, and to analyze quantitatively the structure parameters of the supporting ring and deformed billet dimensions, supplying beneficial directions for the process parameters determination of the upsetting-extruding.
