Discussion on ‘Reconstructed Formulas Calculating Bursting Pressures of the Special Spherical Pressure Vessels Based on Experimental Data’

  • 摘要: 为给比较、选择与确定合适的钢制球形容器爆破压力计算公式提供依据,建立了评价计算公式精度的准确性与集中性指标.基于59组实测数据,分析了钢制球形容器爆破压力4种计算公式的精度.得到如下结论:公式的准确度(爆破压力计算值与实测值之比)平均值与变异系数分别是其精度准确性与集中性的评价指标;对于多层球形容器,当材料屈强比为0.720 9~0.847 5且容器径比为1.053~1.107时,中径公式准确度平均值为0.977 0,变异系数为0.035 4;当材料屈强比为0.336 2~0.618 9且容器径比为1.109~1.257时, 中径公式准确度平均值为1.169 1,变异系数为0.108 3;与其他3种公式相比,中径公式计算钢制薄壁多层球形容器爆破压力精度高,计算钢制薄壁单层球形容器爆破压力集中性高.
