摘　　要：应用ANSYS对FM锻造法进行了数值模拟 ,分析了端部与中部拔长时锻件内应力场分布规律。认为 :合理的锻造工艺参数应由砧宽比、料宽比和压下率三者匹配确定 ,其中压下率起决定性作用 ;对于某一砧宽比和料宽比 ,只有满足一定量的压下率的情况下 ,才能保证锻件心部一定区域内是三向压应力。The FM forging method is simulated by using ANSYS, the stress field of the blank forged at end and middle is analyzed, consider the rational processing parameter should be got from the matching of tool width ratio、blank width ratio and reduction ratio. The reduction ratio is principal among the three processing parameter; The reduction ratio must be greater than a certain value to meet three-direction compressed stress at the center of the blank when tool width ratio and blank width ratio is certain.
