摘　　要：鉴于多孔材料在致密化压制成型过程中空隙变形的复杂性,应用仿真技术分别研究了孔隙率变化和2种不同的压制变形方式对材料变形的影响,通过对应力应变云图以及压制作用力曲线的对比分析,为选择有利的压制方式与模具设计提供了理论数据,并进行了模具强度校核,促进了硬质合金压制装置的设计开发.In view of the complexity of the porous material＇s void deformation being pressing forming, the influence of porosity and two kinds of pressing forming on material deformation is studied by using the finite element analysis. Through the comparative analysis of stress and strain nephogram and the curve of pressing force, the theory data are provided for the choose of advantageous pressing way and the mold design. Further, the strength check of the mold is carried out, which promotes the design and development of suppression device of the hard quality alloy.
