And the honeycomb paper packing has gradually permeated into peoples life. This paper mainly discusses the finite element modeling method of square honeycomb paperboard structure, using SolidWorks to simulate and analyze the performance of the structure. And the main research results are as follows: ?Firstly, after the establish of a three-dimensional model of square honeycomb with a thickness of 20mm cellular core, proceed to the static simulation analysis using the plug-in of SolidWorks Simulation. From the point of stress curve, the in-plane mechanical properties of the square honeycomb can be seen. Secondly, under the same condition of material, conducting static analysis on the height of 10mm and 20mm respectively of square honeycomb cardboard, we can find that the higher of the honeycomb cardboard, the greater the stress it gets. Thirdly, the conclusion we can draw from the stress curve , through the analysis of the two static simulation experiments and the two dynamic simulation ones, is that the concave and convex surface of the
