Abstract：
This study simulated the casting process and the compressive performance of three aluminum honeycomb samples with pore sizes of 10,8 and 6 mm were simulated,and the simulation results were validated by experimental data.ProCAST software was used to numerically simulate the filling and solidification process of aluminum honeycomb,and the casting process was optimized and improved by analyzing simulation results.The effect of pore size on the compressive performance of aluminum honeycomb was analyzed by ABAQUS software with reliable results under experimental verification.The results show that the compression curve of aluminum honeycomb includes three parts:elastic deformation zone,platform zone and compaction zone.The compressive load would increase with the decrease of the pore size and the increase of the relative density.And duration of elastic deformation zone and platform zone would increase in pace with the raising of the pore size.
