摘要
介绍了建立描述粉末金属压制过程数学模型的难点，从理论和应用上详细论述了微观力学方法在粉末成形建模中的应用。分析了这种方法的优劣，探讨了不足的原因。
This paper introduced the difficulties of modeling powdered metal compacting process.In theory and practice,modeling approach was discussed in detail.The merits and shortcoming were shown,and the reason was analyzed.The perspective and suggestion of modeling work were provided as well.
