摘要
根据文[1]所提出的联合上限法和主应力法确定模具表面压力分布的基本原理,计算了圆柱坯料正挤压和十字头锻件镦挤时模具表面的压力分布,所得结果与测定值很吻合.
The pressure distribution over tool in the forward extrusion of the cylindrical billet and the upsetting-extrusion of the cross forging is calculated by the combined UBM/SM approach suggested in the former paper[1].The obtained results are in good agreement with the experimentally determined results.
