【摘要】：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GJB150.16A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。
[Abstract]:Objective to study the test acceleration factor corresponding to the packing and transportation test conditions recommended by GJB 150.16A. Methods based on the equivalent theory of fatigue damage of Miler-Palmgrem model, the mathematical expressions of the driving speed, the material fatigue parameters of the structure and the test acceleration factor are derived. The acceleration factors are quantitatively analyzed for different transportation conditions. Results under different transportation conditions (driving speed) and different structural materials (fatigue parameters), the test acceleration factor varied greatly when GJB150.16A was applied to the package transportation test conditions, and the range of change was 1.6% 9.0. Conclusion the effect of transport condition on acceleration factor should be considered in the design of packaging product transportation test.
