摘　　要：为研究致密度对多孔材料压制变形的影响,针对多孔疏松材料对SHS烧结致密化成型进行有限元分析,应用ANSYS软件研究了压下量为30%时,孔数目不同且均布情况下压制变形的特点。通过分析变形区应力应变分布,孔形状及尺寸变化,材料变形力的变化,得出了致密度对变形力的影响规律。Aiming at the densification of the porous compacts with compression deformation process,the finite element analysis of the compacts were carried out.ANSYS software was applied to simulate the deformation situation of the compacts under the press amount of 30%.From the analysis of deformation and dimensional change,the equivalent strain and strain distribution in the deformation zone,the variation law of the deformation force was analyzed.
