摘要
针对多孔疏松材料在SHS烧结后致密化成型过程中工艺参数难以控制这一特性,采用ANSYS模拟了孔隙体积百分比不同、压坯压下量为30%时疏松孔的变形情况。通过分析变形区应力应变分布、孔形状、尺寸变化以及材料变形力的变化,得出了不同孔隙百分比对加压变形情况的影响规律。
Aiming at the densification process of porous unconsolidated materials sintered by SHS, the compacts were simulated by finite element analysis. The ANSYS was applied to simulate the deformation situation of the compacts under the press amount of 30%, and the other conditions were constant. From the deformation and the dimensional change, the equivalent strain and strain distribution in the deformation zone were analyzed and the variation law of hole-existing material＇s deformation was summarized.
