Key Parameter Function of Wine Cushioning Package of Honeycomb Paper Core

This paper presents methods of cushioning package design. The analysis of existing shortcoming is made when the maximum accelerationstatic stress curve (what is called curve) is applied to the cushion package design, at the same time ,the principle and method steps to get curve are briefly introduced when the stressenergy method is used .the function between the key parameters of cushioning package design is acquired by the stressenergy method .By comparing the data produced with matlab software with the real experimental ones in some paper, the possibilities to get curve of casual drop height and cushion thickness by one-time experiment to get curve with stress-energy method is demonstrated. Based on the function of key parameters of cushioning package acquired, the reversed cushioning package design method is carried out.

Reverse Design for Wine Cushioning Package of Honeycomb Paper Core

Based on the background of cushioning package design for the wine bottles, the analysis on the cushioning properties of honeycomb paper core is presented. The reverse design method based on the function relationship of cushioning package is proposed, to make the cushioning structure design and cushioning dimension design as well as the buffering pad checkout, including strength check, deflection check and creep deformation check to make sure design meets the requirements. The function relation of the maximum acceleration and static stress between arbitrary dropping height and thickness of cushion is obtained. The reverse design method can obtain any curve of any dropping height and any cushioning thickness through several experimental tests. The flexibility, what is more important is that the method can greatly reduce test time, saves the cost of enterprises and technology research & development. The method provides a new way to the cushioning package design.

Research on Cushioning Package Design Methods Based on Infinitive Equations

The cushion design methods based on cushioning coefficient - maximum stress curve were studied. In research work, the cushioning coefficient - maximum stress curve was equivalent to an infinitive equation, and then composed to infinitive equations together with the cushion area and thickness formula. The cushion design methods based on cushioning coefficient - maximum stress curve was characterized as the problem of solving infinitive equations. By this method, the classic cushion area and thickness calculation methods were analyzed. It is believed that the essence of the classic design methods is increasing a restriction to the infinitive equations, as changed the original infinitive equations to posed equations. The research work can help designers deep understanding the traditional cushioning design methods and theories, and can be used to flexible design the cushion structure.

Drop Simulation and Cushioning Package Analysis of 19-Inch LCD

In this paper, drop simulation of 19-inch liquid crystal display (LCD) in three kinds of falling orientations was carried out by Ls-dyna software. By comparing and analyzing the dynamic characteristics, such as the maximum acceleration and stress distribution in the cases of face-down, back-down and bottom-down falling orientations, it was showed the maximum acceleration values were the lowest in the case of back-down falling orientation during the whole drop process, and maximum stress occurred several times in the screen and spread around from the center. The structure and form of LCD cushions were recommended for the reference to the design of cushioning package.

Mechanical Properties of Molded Pulp Pallet

Molded pulp material has been paid much attention for the cushioning package, yet there is no perfect method for evaluate the cushioning properties of different molded pulp configurations, which hampers the advance of molded pulp industry. In this paper an Equivalent Area Theory are put forward in order to study the cushioning properties of this material and the molded pulp pallet is taken as practical example. By experimental and theoretical analyses, the cushion coefficient and maximum stress curve of the molded pulp pallet is obtained, and a design method of molded pulp pallet is established.

Compressive Constitutive Relation for Multi-Layer Corrugated Boards

The investigation into the cushioning properties of multi-layer corrugated boards is a hotspot issue in the packaging field. People one after another investigate into the compressive properties based on experiments. As far as authors' knowledge is concerned, no theoretical research on compressive constitutive relation for multi-layer corrugated boards has ever been reported in literature. Therefore, we investigated into the compressive properties of multi-layer corrugated boards and analyzed their compressive breakage mechanism. The compression curve of multi-layer corrugated boards presents the three sections of linear elasticity, sub-buckling going with local collapse and densification. We constructed the compressive constitutive equation by a subsection function. The equation is standardized by the solid modulus Es of corrugated sandwich materials. Focusing on the structure characteristics, it can express the compression resistance and cushioning properties in the same curve for different basis materials. Comparison between the theory and experiments shows that a good consistency is achieved between theoretical and experimental stress-strain curves. By means of the compressive constitutive equation, the compression resistance and cushioning properties can be evaluated without more experiments, which facilitates the optimization of the structure of the corrugated sandwich structure and the optimized design of the cushioning package.
