摘要
基于三种不同厚跨比的蜂窝纸板在不同湿度条件下的动态压缩应力-应变曲线,构建含相对湿度、蜂窝纸板厚跨比等信息的能量吸收图,结果表明:随着相对湿度的增大,蜂窝纸板最佳能量吸收点向左下方偏移,其单位体积吸收能量的能力减弱。并将该能量吸收图应用于一项工程实例,指导包装设计。
Based on stress-strain curves of honeycomb paperboaris with different thickness-to-length ratios under dynamic compression in different relative humidities, the energy-absorption diagrams were modeled and constructed, they included the information of thickness-to-length ratios and relative humidity conditions. It was shown that the optimal energy-absorption point shifts to the lower left and the energy-absorption capacity per unit volume decreases with increase in relative humidity. The energy-absorption diagram was used in a project case to guide the package design.
