摘　　要：目的采用LS-DYNA软件中的MAT274纸张本构模型,研究瓦楞纸板边压强度有限元仿真计算问题,并结合理论和试验结果验证模型的可靠性。方法参照瓦楞纸板边压强度测试试验标准,使用ANSYS和LS-PREPOST软件建立与此标准相吻合的瓦楞纸板边压强度计算的有限元模型;采用边压强度试验及Li的简化公式和Garbowski的改进经验公式,分别得到瓦楞纸板的边压强度;对相关结果进行对比分析,以验证瓦楞纸板边压强度仿真计算模型的可靠性。结果针对B型、C型2种瓦楞纸板,采用以上方法得到其压缩过程及压缩曲线或边压强度的试验、理论和有限元计算结果。结论试验和仿真得到压缩过程中样品的变形模式和压缩曲线,以及边压强度理论、试验和仿真值结果的吻合性,证明了有限元模型的可靠性。这为瓦楞纸板设计应用提供了重要的参考和指导。The work aims to investigate the finite element calculation of edge compression strength of corrugated paper fiberboard using the MAT274 paper constitutive model in LS-DYNA,and validate the model's reliability through comparison between theoretical and experimental results.A finite element model for the calculation of edge compression strength of corrugated paper fiberboard was established using ANSYS and LS-PREPOST software,according to the standard for edge compression strength testing of corrugated paper fiberboard.The edge compression strengths were also obtained through edge compression strength tests,Li's simplified formula,and Garbowski's modified empirical formula.A comparative analysis of the results was conducted to verify the reliability of the finite element model.For the corrugated paper fiberboard with B,C flute types,the compression process,compression curves,and edge crush strengths were obtained according to the above methods.The agreement of deformation modes and compression curves of the specimens during compression,as well as the theoretical,experimental,and simulated values of edge compression strengths,verifies the reliability of the finite element model.This provides important references and guidance for the design and application of corrugated paper fiberboard.
