| 摘 要： | 本文主要采用有限元法分析复合气瓶的爆破,按最大应力准则和最大应变准则预测爆破压力,并与《DOT CFFC》标准规定的最小爆破压力进行比较,计算误差百分比,由误差百分比分析得出,按最大应变准则预测爆破压力较为接近最小爆破压力,对工程实践有较大的指导意义。

| Abstract: | In this paper,the bursting of composite cylinders is analyzed with the finite element method.The burst pressure is predicted according to the maximum stress criterion and the maximum strain criterion.The predicted results are compared with the minimum burst pressure regulated by the DOT CFFC standard,and the percentage error is calculated.By analyzing the percentage error,it can be concluded that the burst pressure predicted with maximum strain criterion is more approximate to the minimum burst pressure.The finite element analysis results in this paper are conducive to the engineering practice. |
