摘要
以牛奶包装用0201型C楞三层瓦楞纸箱为例,通过试验数据分析各个设计变量的统计特征;以纸箱承载达到其极限抗压能力为主要失效模式,建立了瓦楞纸箱抗压强度可靠性分析方法;通过敏感性分析定量评估了各个设计变量对瓦楞纸箱抗压能力的影响程度;计算了随机安全系数的变动范围,指出现行的强度设计方法是偏于安全的。
The reliability analysis formulation based on compressive ultimate strength of corrugated fibre box which is applied to the packaging container for MiaoShi milk was presented. The statistical property of design variables was obtained by statistical analysis of the data from experiment. The effect of design variables on compressive strength of packaging container can be evaluated quantitatively by sensitivity analysis. According to the calculated range of random safety factor the conclusion can be drawn that the current design method is overdesigned.
