摘　　要：借助商用有限元软件MSC.SuperForm2005对锥形辊穿孔过程进行三维热力耦合模拟,研究顶头前伸量对穿孔力参数的影响。结果表明,在锥形辊穿孔过程中,当保持其它参数不变时,随着顶头前伸量的增加,轧制力和顶头轴向力均减小,而导盘力略有增加。With the aid of commercial FE code MSC. SuperForm 2005, a 3-D coupled thermo-mechanical analysis of the cone-type piercer was conducted. Variation of power parameters in the case of different plug advance was obtained. The analysis shows that during the cone-type piercing process, if other parameters are fixed, with the increase of plug advance, the rolling force and plug force both decrease, the guide-disc force increases a little.
