摘要
基于双瓦楞纸板蠕变-时间曲线的分段式经验公式及其特征系数,运用粘弹性理论,建立了双瓦楞纸板蠕变特性的两种力学模型,并验证了模型的有效性。结果表明,这两种力学模型都能反映双瓦楞纸板的蠕变特性,第2种力学模型相对第1种简洁、方便,而第1种力学模型比第2种更能接近蠕变试验结果。
On the basis of the piecewise experiential formula and its characteristic factors of creep and time curves of double-wall corrugated paperboard, two kinds of mechanical models of creep property were established by using theory of viscoelasticity, and the validity of two models was verified. The result showed that both of the two mechanical models can reflect the creep properties, the second kind of mechanical model is simpler andmore convenient than the first one, yet the first kind of mechanical model is much close to the experimental results.
