摘要
通过常规的爆破试验获得承压设备的塑性破坏载荷——爆破压,需要消耗大量的人力和财力,有时受试验条件的限制,无法由试验获得承压设备的爆破压。采用有限元分析软件ANSYS对无缺陷含接管圆筒形容器进行弹塑性有限元分析,可获得爆破压计算值。计算值与试验实测值比较结果表明,采用弹塑性有限元分析方法能够模拟含接管圆筒形容器的塑性失效过程和估算其爆破压,并且可大大节省人力和财力。
It costs large amount of man power and money to determine pressure vessels＇ plastic failure load, namely, blast pressure, through conventional blasting tests. Even though, sometimes limited by test conditions, the blast pressures are unable to get from tests. However, by applying elastic-plastic finite element analysis to no-defect cylindrical vessel with linking tube using ANSYS, blast pressure can be calculated. Compared with measured values, results show that finite element method is able to simulate the process of vessel plastic failure and estimate its blast pressure, significantly reducing man power and costs.
