中文摘要:
      目的 基于Ansys研究大中型运输包装堆码过程中纸质外围框的双A型瓦楞纸板失稳问题。方法 使用Ansys软件并结合APDL语言构建双A型瓦楞纸板有限元模型,然后对该模型进行特征值屈曲分析,得到使纸板发生屈曲的最小临界载荷和屈曲后纸板的变形情况,最后改变纸板的高度与长度,再进行多次特征值屈曲分析,分析纸板的高度和长度与纸板临界屈曲载荷的关系。结果 纸板的临界屈曲载荷与纸板的长度成正比,与纸板高度的平方成反比。结论 纸质外围框双A型瓦楞纸板更加适合包装高度较低的产品,以减少失稳的可能性,当双A瓦楞纸板所承受的力大于临界屈曲载荷时,可以在瓦楞纸板的外表面添加胶合板加强筋,承担一部分的承载压力,从而使瓦楞受力在临界屈曲载荷之下。
英文摘要:
      The work aims to study the instability of double-deck A-type corrugated board which is used to constitute corrugated box in the process of stacking for large-/medium-sized shipment packaging via Ansys. First, by using software Ansys in combination with APDL language, the finite element model of double-deck A-type corrugate board was constructed. Then through analyzing the eigenvalue buckling of such model, the minimum critical buckling load which led to the buckling of the board and the deformation after the board buckled could be calculated. Finally the length and height of the board were changed and repeated eigenvalue buckling analysis was carried out for many times to analyze the relation between board length & height and the critical board buckling load. The critical buckling load of the corrugated board was in direct proportion with its length and was in inverse relation with the square of its height. In conclusion, corrugated box constituted by double-deck A-type corrugated board is more applicable to products of lower height, so as to reduce the possibility of instability. But when the force applied on the double-deck A-type corrugate board exceeds the critical buckling load, the stiffener can be added to the outer surface of the corrugate board to share part of the bearing pressure, thus ensuring the board stress to be under the critical buckling load.
