Abstract


Honeycomb paperboard is an environmentally friendly packaging materials , light weight, stiffness and specific strength advantages , mainly used in the manufacture of crates, pallets and cushion, . However, due to the production equipment , production process , production costs , in particular, is a regular hexagon honeycomb paper core structure of the limitations of many other reasons , the current the honeycomb paperboard exist side low compressive strength , poor performance of the initial buffer can not be folded defect , constraints in packaging applications . Lack of regular hexagonal honeycomb cardboard structure by theoretical calculation , simulation analysis and experimental demonstration , a more systematic study of a new structure - the mechanical properties of the diamond-shaped sandwich honeycomb cardboard . Based on procaine cuff - Du Qinghua type theory , comparative analysis of the mechanical properties of the two Fengwozhiban differences reveal the underlying trend of the core size of the structure and properties , and predict the important physical performance of the diamond-shaped honeycomb cardboard . The establishment of a the honeycomb cardboard three-dimensional finite element model , the actual working conditions in the application of ABAQUS software simulation cardboard pressure , cushioning and compression capability of two cardboard structure simulation analysis and assessment made ??is consistent with the theoretical analysis conclusions. The the rhombus Fengwozhiban molding process to explore , and homemade standard sample comparison test sample static compression and dynamic impact performance . The test results show that : the control of of honeycomb paperboard axial compression capability and vertical and horizontal direction can be achieved by changing the core structure and size to reach the improvement Fengwozhiban cushioning and lateral pressure strength of purpose . The research results obtained demonstrate the scientific and feasibility of the diamond-shaped sandwich honeycomb paper , laid the foundation for in-depth study of this new diamond-shaped honeycomb cardboard packaging materials , and the popularization and application in the field of packaging .
