摘要
利用传统经验公式计算圆筒形压力容器的爆破压力,将计算结果与实测结果对比,分析计算误差的分布特性。在此基础上参照建立传统经验公式的方法,并结合传统经验公式的构成特点,对计算圆筒形压力容器爆破压力的几个经验公式进行改进,并利用文献中的实测数据对改进公式进行验证。验证结果表明,与原公式相比,改进公式具有更高的计算精度。这说明改进公式具有一定实用意义,相应的改进方法是合理的,可在类似问题的研究中推广应用。
By using several traditional empirical formulas, the bursting pressures of some cylindrical vessels were calculated, a comparison between calculated and tested results was performed, and the characteristics of error cingula were analyzed. Based on the characteristics of error cingula, referring to the methods constructing traditional empirical formulas and taking the structural characteristic of the original formulas into consideration, the traditional empirical formulas were amended. Moreover the amended formulas were validated by experimental data. The validation results indicate that the accuracy of the amended formulas is higher than that of the traditional empirical formulas, which implies that the amended formulas are practically useful in design of the discussed special spherical pressure vessels, the related amendment methods are reasonable and can be used in researches of analogous problems.
