基于等效抗弯刚度原理，对瓦楞纸板进行了简化，得到了瓦楞纸板的简化模型——等效板，并利用Ansys Workbench有限元软件对等效板有限元模型进行了屈曲分析，最后通过试验进行了验证。结果表明，通过抗弯刚度得到瓦楞纸板简化模型的方法简单可行。

A simplified model of corrugated cardboard-equivalent plate was established by simplifying corrugated cardboard based on the principle of equivalent flexural rigidity. Bending analysis of equivalent cardboard was carried out using the Ansys Workbench software and the result was verified by experiment. The results showed that the method to establish simplified model of corrugated cardboard through flexural rigidity is simple and feasible.
