摘要:
运用数理统计的假设检验理论,建立了有关因素对容器爆破压力计算公式精度影响的评价方法. 基于52组钢制薄壁单层球形容器爆破压力实测数据,分析了材料屈强比对中径公式与福贝尔(Faupel)公式精度的影响. 研究表明:对于材料屈强比为0.336 2~0.618 9且径比为1.109~1.257的单层球形容器,屈强比的变化对中径公式的精度没有显著影响;中径公式的集中度显著高于福贝尔公式. 将屈强比范围调整为0.449 8~0.618 9且径比范围调整为1.114~1.257时,福贝尔公式的精度得到显著提高,且集中度显著高于中径公式.
Abstract:
To evaluate the relative factors affecting the accuracy of the vessel burst pressure calculation formula, we established an evaluation method by using the theory of statistical hypothesis testing. Based on the burst pressure measured data of 52?sets of?spherical vessels with single-layer steel, ?the influences of materials yield ratio on?the precision?of Faupel formula and mid-diameter formula were analyzed.?The study shows that the change of material yield ratio has no significant effect on the mid-diameter formula’s accuracy, and the mid-diameter formula’s concentration is higher than that of Faupel formula, for the spherical vessels with the materials yield ratios between 0.336 2 and 0.618 9, and the diameter ratios between 1.109 and 1.257. The Faupel formula’s precision is significantly improved, and the Faupel formula’s concentration is higher than that of the mid-diameter formula when the materials yield ratios were adjusted from 0.449 8 to 0.618 9, and the diameter ratios from1.114 to 1.257.
