| 目的 研究了 GJB 150.16A 推荐的包装运输试验条件对应的试验加速因子 。 方法 基于Miler-Palmgrem模型的疲劳损伤等效基本理论， 导出了车辆实际运输时的行驶速度、结构的材料疲劳参数与试验加速因子之间的数学表达式， 并对不同的运输工况进行了加速因子的定量分析。 结果 不同的运输工况（行驶速度）和不同的结构材料（疲劳参数）， 当应用 GJB 150.16A推荐的包装运输试验条件时， 其试验加速因子相差很大， 变化范围为 1.6~9.0。 结论 设计包装产品的运输试验时要考虑运输工况对加速因子大小的影响。 |

| Objective To investigate the experimental accelerated factors corresponding to the package transportation test condition recommended by GJB 150.16A. Methods Based on the fatigue damage equivalence basic theory of the Miler-Palmgrem model, a mathematical equation between the experimental accelerated factor, actual vehicle speed and fatigue parameter of the tested structure was proposed. And a quantitative analysis was conducted on accelerated factors for different application status. Results Under the package transportation test condition recommended by GJB 150.16A, the accelerated factor differed a lot with different transportation conditions (vehicle speed) and structural material (fatigue parameter), ranging from 1.6 to 9.0 simulating different application status. Conclusion Thus, taking the effect of application status on accelerated factor into consideration while designing packaging products transportation testing is important. |
