摘要
利用传统经验公式计算了一系列特种球形压力容器的爆破压力,将计算结果与实测值对比,分析了计算误差的散布特性.在此基础上,利用爆破压力的实测数据构建了球形压力容器爆破压力的计算公式,并对其精度进行了两类检验,一是将计算结果与同类型特种球形压力容器的实测数据对比,二是将计算结果与普通球形压力容器实测数据对比.结果表明,与原经验公式相比,所构建公式的精度有明显提高,同时表明构建爆破压力计算公式的方法是合理的,并可在类似问题的研究中推广应用.
With several traditional empirical formulas,the bursting pressures of the special spherical pressure vessels were calculated,comparison between the calculated and tested results was performed,and the characteristics of the related error ranges were analyzed.Based on the experimental data of the bursting pressure,several reconstructed formulas were given and the accuracy of their calculated results was examined in two ways.O ne way was to compare the results with the experimental data of the same kind of special spherical vessels：the other was to compare the results with the experimental data of the general spherical vessels.It turns out that the results of the reconstructed formulas are far more accurate than those of the traditional empirical formulas,which implies that the reconstructed formulas are practically useful in design of the discussed special spherical pressure vessels,and the related reconstruction method is reasonable and helpful to the research of similar problems.
