For confirming the results , a full - size model ( dj / dj = 0 . 6 , t / t = 1 . 5 ) was analyzed by means of strain gauge test . the reliability of finite element analysis was proved because the results basically accorded with that of the test . secondly , in this paper , in order to carry out a fair assessment of the reinforcement design on spherical shell with transnormal nozzle , a comparison of reinforcement method was done between jb4732 - 1995 steel pressure vessels ? esign by analysis appendix a4 and hg20582 - 1998 specification for stress calculation of steel chemical vessels 为了验证ansys分析结果的可靠性,对其中一组参数下(开孔率0 . 6 、厚度比1 . 5 )的模型容器,采用电测法进行了应力测试,并将得到的实验结果与有限元结果进行了比较,二者在应力分布状况和大小上均基本吻合,证明此种结构运用ansys进行分析,其结果是完全可靠的。
