摘要

目的本研究的主要目的是确定瓦楞纸板各向异性机械特性的特征,同时模拟其在各种跌落条件下的跌落缓冲动态效应。通过在 ANSYS LS-Dyna 中开发蜂窝材料模型,引入了一个有效的各向异性构成模型,并建立了一个有效的方法,以便从获得的测试数据中有效确定材料参数。通过将模拟结果与五种跌落条件(包括底部跌落、正面跌落、侧面跌落、30°侧面跌落和边缘跌落)的实验数据进行比较,对模型进行了验证。研究结果该研究建立了一种快速有效的方法来模拟瓦楞纸板在各种跌落条件下的跌落缓冲性能,结果与实验数据吻合良好。

Drop cushioning dynamic effects of corrugated cardboard with effective anisotropic constitutive model
PurposeThe primary objective of this study is characterizing the anisotropic mechanical properties of corrugated cardboard and simultaneously simulating its drop cushioning dynamic effects under various drop conditions.Design/methodology/approachStatic and dynamic tests were conducted on corrugated cardboard to obtain adequate experimental data in different directions. An effective anisotropic constitutive model is introduced by developing the honeycomb materials model in ANSYS LS-Dyna, and an effective approach is established toward effectively determining the material parameters from the test data obtained. The model is validated by comparing simulation results with experimental data from five drop conditions, including bottom drop, front drop, side drop, 30° side drop and edge drop. Additionally, simulations are conducted to study the cushioning performance of the packaging by dropping the corrugated cardboard at different heights.FindingsThe study establishes a fast and effective approach to simulating the drop cushioning performance of corrugated cardboard under various drop conditions, which demonstrates good agreement with experimental data.Originality/valueThis approach is of value for packaging protection and provides guidance for stacking of packaging during transportation.
