“…Structures composed of paper‐based materials (such as honeycomb paperboard, corrugated paperboard, and paper tubes) are often idealized as rigid plastics in the study of axial crushing, 44,48,49 because the energy absorption during the elastic phase is usually not significant. The Super Folding Element (SFE) theory, first proposed by Wierzbicki, 6 calculated the energy dissipation of the corner element, then Chen 50 simplified the theory and proposed Simplified Super Folding Element (SSFE)theory, the above two theories are more accurate in predicting the mean crushing force for right‐angle elements, but the prediction deviates more for acute and obtuse angles.…”

In this paper, a new multi-cell lattice honeycomb paperboard was designed based on the expansion manufacturing process, aiming to improve the load-bearing capacity and energy absorption of the honeycomb paperboard. Quasi-static axial crush experiments were conducted on multi-cell lattice honeycomb paperboard (MHC) and standard honeycomb paperboard (HC), and the out-of-plane crushing response and energy absorption of MHC and HC are compared. The deformation mode of MHC is discussed in detail. A typical folding element is selected, and a theoretical model is developed to predict the plateau stress of the MHC. The results show that under the same structural and cell length dimensions, the peak stress of MHC is 3.3 times higher than that of HC, the plateau stress and energy absorption are 3.9 times higher than that of HC. Under the same relative density conditions, the peak stress of MHC is enhanced by 10% over HC, and the plateau stress and energy absorption are enhanced by 30% and 29%, respectively. The predicted plateau stress from the theoretical model compares well with the experimental values. The great potential for industrial applications of multi-cell lattice honeycomb paperboard based on an expansion manufacturing process is demonstrated, with minimal modifications to the manufacturing process but with a significant increase in load-bearing capacity and energy absorption. These results could be used as a reference for the design and improvement of honeycomb structures and other similar structures.

“…When the method is adopted to solve the nonlinear contact problem, the convergence of the iteration needs to be considered at every step [18][19][20][21][22]. Assume q i is the exerted load, p i is the force vector balanced with internal force, then q i − p i is the unbalanced force.…”

This study presents a use case of Finite Element Method and comparative experimental studies on a subproblem in packaging machines. The variables in the vacuum picking system including baffle height, back pressure and friction between sheets are evaluated through simulations and experiments. It is found that baffle height, back pressure F and friction between sheets are all critical in successful operation of vacuum picking cardboards from in-feed magazine. This study is of some practical value for the implementation of vacuum picking board sheets from in-feed magazine on many types of packaging machinery.

Honeycomb paperboard's out‐of‐plane bearing performance is one of the important properties in packaging field application. Further improvement of its bearing performance has important value in engineering practice. In this paper, a honeycomb core structure was designed, and the bonding dimension and manufacturing process were designed. The mechanism of out‐of‐plane quasi‐static compression deformation of reinforced honeycomb paperboard was analyzed by experiments. The theoretical model of out‐of‐plane platform stress was constructed by applying the plastic deformation, plastic energy dissipation and energy conservation theory. The results show that the improved structure can be mechanically bonded in a flat state with less technological changes. Under the same honeycomb core material and core size parameters, the bearing strength of the improved structure increases by an average of 3.9 times to conventional structure. In order to meet the same compressive strength requirement, the improved structure can reduce the performance requirements of honeycomb core material or increase the core size compared with the conventional structure. When the honeycomb core cell is larger, the tension on the core layer required for the production process is reduced. The theoretical and experimental data are in good agreement with each other, and the relative errors are all less than 13%.
