由于瓦楞纸的屈曲机理非常复杂，难以准确预测屈曲强度，利用非线性有限元的方法对某瓦楞纸筒进行了非线性屈曲分析，计算出了其极限承载能力，分析了影响其承载性能的主要因素。结果表明，采用非线性有限元方法对瓦楞纸包装结构进行屈曲分析是可行的，分析结果对瓦楞纸包装设计具有较好的参考价值。

It is difficult to precisely predict the ultimate buckling strength for the complex buckling mechanism of corrugated board. Nonlinear buckling analysis of corrugated board column was carried out by using nonlinear finite element method, the ultimate carrying capacity was calculated, and the main factors influencing carrying capacity of the corrugated board column was analyzed. The results showed that it is feasible and valuable to carried out buckling analysis of corrugated board structure using nonlinear finite element method; the result can be reference for structure design of corrugated paper package.
