摘要

瓦楞纸板作为产品运输包装的承载与缓冲基础材料，其使用过程中的性能保持性至关重要。运输振动将引起纸板疲劳破损，导致其相应性能的变化。对单瓦楞纸板进行加速度为0.5－2.0g、振动频率为20Hz的疲劳振动试验；进行瓦楞纸板的准静态压缩、跌落冲击试验，测定其承载能力与冲击加速度。结果表明，随着振动次数、振动强度的增加，纸板的承载能力、剩余屈服应力显著降低，缓冲性能下降。在此基础上，基于瓦楞纸板冲击试验数据，分析不同振动次数对瓦楞纸板的冲击最大加速度和缓冲系数的影响，获得了瓦楞纸板冲击最大加速度—静应力—振动次数、缓冲系数—最大应力—振动次数三维关系。研究表明瓦楞纸板存在疲劳破坏效应，研究结果为瓦楞纸板的疲劳缓冲包装设计提供技术依据

Abstract

The fatigue vibration test of corrugated fiberboard was conducted. The influence of the number of vibration and vibration acceleration on load capacity of corrugated fiberboard was determined, compared with non-vibrated corrugated fiberboard. The load capability of corrugated fiberboard after fatigue vibration depends on not only circulation number of loading but also on the vibration peak acceleration and frequency. The change of stress-strain and cushioning coefficient after the vibration test is studied by dynamic compression experiment. According to the test result, the three-dimensional relations about dynamic cushioning coefficient-maximal stress-vibration number and maximal acceleration-stress-vibration number were developed. The influence of fatigue on the properties of cushioning material should be considered, in order to meet the anticipated packaging effect.
