分布拟合检验法在确定运输包装力学环境中应用

The Application of Distribution Fitting Check Method in the Determination of Mechanical Conditions of Transport Packages

应用概率统计的数学方法——分布拟合检验法,讨论了包装件运输过程中受到各种冲击载荷的建模问题,首先用皮尔逊检验法确定一定重量包装件跌落高度—发生频率之间分布规律,然后用R检验法检查不同重量包装件的跌落高度—发生频率之间的两总体是否具有相同的概率分布规律。并对引用的两个测试实例进行了统计分析和计算。

In this paper, the probabilistic method—distribution curve fitting check method is used to anylyse the mode of the shock loads acted on the transport package during transportion. First, the Pearson Check Method is used to determine the distribution of drop heights and occurrence frequency of the packages with given weights. Then, R-Check Method is used to check whether or not there exists a similar probabilistic distribution of the drop heights and the accurrence frequency of the packages with different weights. Two examples are cited to make the calculation. One result demostrates that the distribution is of logarithmic normal distribution, while the other one is not.
