玉米秆粉粒体压制成型模型的研究

Research on the Compaction Modelling of Corn Stalk Powder

通过密闭型圆筒准静态压缩试验，推导并建立了玉米秆粉粒体压制成型的本构方程，并用有限元模型进行了模拟。对压制成形的网格变形图、应变分布以及载荷位移曲线的分析表明，理论结果与试验结果一致。

This paper describes the constitutive equations and mechanical behavior of corn stalk powder in compaction process by using the quasi static compression in a cylindrical closed die,and analyses the distribution of stress and strain.The constitutive equations are established,and the simulation for compaction process of corn stalk powder is studied with FEM also.The theoretical results agree with the experimental ones.
