钢制薄壁内压容器爆破压力的概率分布研究

应用数理统计方法 ,对钢制薄壁内压容器的爆破压力进行了分析 ,得到如下两个结论 :①在显著度为 5 %时 ,描述爆破压力实测值与预测值之比的随机变量符合正态分布 ;②在置信度为 99%时 ,分析得到了该随机变量分布参数的取值范围。

Research on Probability Distribution of Burst Pressure for the Thin-steel-wall Internal Pressure Vessel

In this paper,by using the method of statistics,the burst pressure for the thin steel walled internal pressure vessel is analysis.Two results shows that:1.the ratio is a random variable with normal distribution that of the burst pressure and their theory expected value complied,and with the marked of 5%;2.with the confidence limit of 99%,the distribution parameter of the random variable is obtained.
