摘要
利用有限元对某球形爆炸容器的卡箍式人孔门结构进行了强度分析。通过数值模拟计算,得到结构各部分的等效应力分布区域及大小,计算结果表明球形爆炸容器设计中,卡箍式人孔门结构是一种合理的设计结构,计算对爆炸容器的强度校核及人孔结构的优化设计有一定的指导意义。
The finite element method was applied to analyze the strength of man hole with yoke of blast chamber. Through three numerical modeling,the zone and magnitude of maximal equivalent stress in the structure were obtained. The conclusion has some significance for the blast chamber’s strength checking and optimum design.
