              摘要: 包装容器及其内容物在流通过程中,会因车速、路况等因素受到不同程度的冲击,这些冲击造成了包装容器绝大部分的
              损伤。为研究冲击对不同材料属性包装容器易损点的损伤规律,对 8 条实测道路信号分别进行冲击的提取,得到 20% 含有大
              幅值冲击的非高斯信号和 80% 较低振动幅值的高斯信号。在有限元软件中进行瓦楞纸箱和塑料周转箱的建模,计算各信号
              段的损伤占比。结果表明:20% 含有大幅值冲击的非高斯信号在瓦楞纸箱易损点造成的损伤占总损伤的 75% 以上,其中中型
              卡车的冲击信号造成的损伤可达 95%;20% 含有大幅值冲击的非高斯信号在塑料周转箱易损点造成的损伤占总损伤的 97%
              以上,其中中型卡车的冲击信号造成的损伤可达 99%。冲击信号损伤占比与材料属性参数 b 密切相关。

              Abstract: During the circulation process, packaging containers and their contents will be subject to varying degrees of vibration and
              shock due to factors such as vehicle speed and road conditions. These shocks cause most of the damage to packaging containers. In
              order to study the damage rules of vulnerable points of packaging containers with different material properties caused by shock, 8
              measured  road  signals  were  extracted  for  shock  respectively,  and  20%  of  the  non-Gaussian  signals  containing  large-amplitude
              shocks  and  80%  of  the  Gaussian  signals  with  lower  vibration  amplitudes  were  obtained.  Model  corrugated  cardboard  boxes  and
              plastic turnover boxes in finite element software, and calculated the damage proportion of each signal segment. The results show
              that the damage caused by 20% shock signal at the vulnerable points of corrugated box accounts for more than 75% of the total
              damage, and the damage caused by the shock signal of the medium-sized truck can reach 95%. The damage caused by the 20%
              shock signal at the vulnerable points of the plastic turnover box accounts for more than 97% of the total damage, of which the dam⁃
              age caused by the shock signal of the medium-sized truck can reach 99%. The damage ratio of shock signal is closely related to ma⁃
              terial property parameter b. The conclusions can provide reference for the design optimization and laboratory evaluation of packag⁃
              ing containers.
