Accurate prediction of loads on containers and their pertinent securing systems is important for efficient handling and transportation of the containers as well as for optimization of the applied securing systems. Container stacks react nonlinearly to the excitation forces. This paper presents a nonlinear finite element method developed to predict the structural response of containers and their associated securing systems when subjected to excitation forces. The method is verified against another finite element model and a comparison study involving several numerical approaches is conducted. The verification shows that the proposed method can predict the reaction force on container and securing items with sufficient accuracy.

准确预测集装箱及其相关系固系统上的负载对于集装箱的有效装卸和运输以及应用的系固系统的优化非常重要。集装箱堆垛对激振力的反应是非线性的。本文提出了一种非线性有限元方法，用于预测集装箱及其相关固定系统在受到激励力时的结构响应。该方法针对另一个有限元模型进行了验证，并进行了涉及几种数值方法的比较研究。验证表明，所提出的方法可以足够准确地预测集装箱和固定物品上的反作用力。
