中文摘要:
      目的 研究纸板在模压过程中的形变和分层现象。方法 模压是用纸板生产纸盒的重要环节, 模压过程容易造成纸板分层。用正交各向异性弹塑性连续体模型描述各层纸板的力学特性, 用内聚力模型描述纸板层间的粘合和在模压过程中的分层, 用有限元软件Abaqus模拟纸板模压, 再现纸板变形过程, 预测模压对纸板分层的影响。结果 从仿真结果得到, 模压造成纸板分层, 这与真实实验一致。结论 力学模型能描述纸板在模压过程中的形变和分层特性。
英文摘要:
      This experiment aimed to study the deformation and the delamination of cardboard during the creasing process. The creasing process was an important link during production of paper box by cardboard, however, this process was likely to cause paperboard delamination. An orthotropic elastoplastic continuum model was used to describe the mechanical property of each layer of cardboard. A cohesion model was used to describe the bonding and the delamination during creasing. The finite element software Abaqus was used to simulate creasing and the cardboard′s distortion and to forecast influence of creasing on paperboard delamination. According to the simulation results, the creasing process can cause paperboard delamination, which was consistent with the real test. The mechanical model can describe the deformation and the delamination of the cardboard.
