Construction method of energy absorption curve of honeycomb paperboard under different environmental humidities

Abstract

The invention provides a performance prediction and optimization method of a honeycomb paperboard, and relates to a construction method of an energy absorption curve of the honeycomb paperboard under different environmental humidities. The method comprises the following steps of: constructing relationships among the energy absorption capability of the honeycomb paperboard, the yield strength and the elasticity modulus of honeycomb base paper, the thickness spaning ratio of honeycomb cell walls and the environmental humidities; and drawing the relationship between the standardized energy absorption and the standardized stress in each phase on a coordinate system with logarithmic scales, thereby obtaining the energy absorption curve of the honeycomb paperboard with different thickness spanning ratios under the different environmental humidities. By utilizing the method, the energy absorption curve of the honeycomb paperboard under the different environmental humidities can be drawn quickly and accurately while a large number of tests are not required, namely, the best energy absorption point of the honeycomb paperboard which is of a given material configuration under the different environmental humidities can be found; the structure parameters of the honeycomb paperboard can be acquired reversely according to the conditions of the environmental humidities of logistics and the requirements of the buffering energy absorption of products. Thus, the beneficial reference for the optimal design of the buffering packaging of the honeycomb paperboard is provided.

Description

technical field [0001] The invention belongs to the field of performance prediction and optimization of honeycomb paperboard, and relates to a method for predicting and evaluating the energy absorption performance of honeycomb paperboard under different environmental humidity conditions. Background technique [0002] The damage and failure of products caused by logistics vibration and impact is very serious. The economic loss caused by this in my country has exceeded 100 billion yuan every year. The loss caused by the damage of some special products caused by improper packaging protection is even more immeasurable, such as weapons. , ammunition, antiques, etc., so it is necessary to design corresponding protective packaging. The designed protective packaging should be able to absorb and consume the impact energy through the deformation of the cushioning packaging material itself in the event of a drop impact, so that the maximum force transmitted to the product is lower than ...
