| 目的 研究采用U型瓦楞纸板进行缓冲包装设计的量化方法。方法 通过建立不同相关密度单层U型瓦楞纸板有限元模型，得到不同压缩速度下瓦楞纸板的应力-应变数据和单位体积吸收能量-应力数据，进行数据拟合得到相关密度方程和应变率方程。结果 随着相关密度的增加，瓦楞纸板的最大许用应力也在不断增加；从单位体积吸收能量-应力曲线上看，不同相关密度瓦楞纸板的最大许用应力包迹线呈线性关系；拟合的应变率方程和相关密度方程经验证可以方便高效地进行缓冲包装设计。结论 拟合的应变率方程和相关密度方程使用方便、快捷、高效，减少了查表法带来的误差，在实际生产中具有一定意义。 |

| The paper aims to research quantification method of using U corrugated board to design the cushioning package. By establishing finite element models of U corrugated boards with different relative density, the stress-strain data and energy volume stress data of corrugated boards at different compression speeds were obtained. The density equation and strain rate equation were obtained by fitting data. With the increase of density, the corrugated maximum allowable stress also increased; from the point of view of unit volume, the maximum allowable stress for corrugated board of different density was linear; the fitting equation of strain rate and relative density equation had been proved to be convenient for cushioning packaging design efficiently. The fitted strain rate equation and correlation density equation are convenient, fast and efficient. It reduces the error caused by look-up table method, and has certain significances in actual production. |
