Research And Application On In-Plane Properties Of Honeycomb Paperboard Based On ANSYS

Focused on different core paper, facial paper, side length, thickness and aperture ratio of honeycomb paperboard, this paper used both in-plane static compression experiment and finite element analysis method, how raw material and structure influence the in-plane properties of honeycomb paperboard, have been obtained. The mechanical properties and deformation mode of the honeycomb paperboard in the in-plane compression conditions were also analyzed. According to the in-plane mechanical properties of honeycomb paperboard, this paper chose a product packaging design, analyzed its compressive properties, and put forward scheme of the enhancement compressive performance about the honeycomb paperboard boxes.Firstly, this paper tested the physical properties of the paper. The results showed that there were not direct relationship about elastic modulus and yield strength of base paper. Longitudinal elastic modulus and yield strength of base paper were greater than the lateral value.The choice of base paper should be considered in calculating the orthogonal anisotropic.Then, the different raw paper and structure were tested by in-plane static compression experiment,how different factors influence the flatwise compressive properties and compressive strength of honeycomb paperboard, have been obtained.The results showed that the facial paper had great influences on the in-plane properties of honeycomb paperboard,the yield strength of the facial paper were determines compression strength of the honeycomb paperboard.The side length,thickness and aperture ratio of honeycomb paperboard had great influence for in-plane properties of honeycomb paperboard.The in-plane mechanical properties of honeycomb paperboard were analyzed and simulated based on finite element analysis method.The in-plane mechanical properties and compression deformation rule of honeycomb paperboard were obtained. The results showed that stress and deformation of facial paper were much bigger than those of core paper, and in-plane mechanics properties of honeycomb paperboard mainly depended on facial paper. Facial paper-nearby cell position appeared stress concentration phenomenon, and cell position firstly appeared crushing deformation. When pressed in different directions, the deformation and bearing model of honeycomb paperboard is not the same. The wave range of lateral compression is smaller than that of longitudinal compression stress. To compare the results more directly, there is satisfactory agreement between the numerical analysis and the experimental measurements. The finite element method could quickly build the finite element model of honeycomb paperboard and analyze its properties.Finally, this paper chose a refrigerator for honeycomb packaging design and analyzed compressive properties by ANSYS software with finite element analysis method. The results showed that the central part of each side and four edge place of the boxes appeared stress concentration. And this paper put forward by reducing cellular side length or increase the board thickness scheme of the enhancement compressive performance of the honeycomb paperboard boxes by reducing the side length of the hexagon or increasing the thickness of honeycomb paperboard, provided some valuable Suggestions for the production, avoided the emergence of excessive packaging and less packaging.
