摘要
本文分析了ＤｅｃｏｃｋＪ公式的内在缺陷，采用适当的模型对此缺陷进行了修正，并用４１个实验数据进行了计算比较。结果表明，修正的ＤｅｃｏｃｋＪ公式比原式的计算精度更高，同时还表明接管臂部接点邻域内筒体周向弯矩及壳元翘曲对接管应力集中有显著影响。
he internal defects of Edcock J formula were anal- ysed and revised by using suitable models ,and a calculating comparison was conducted with 41 experimental data. Theresult showed that revised Cecock J formula was more ac-curate ,and circumferential bending moment of cylinders and shell warps in connection point neighborhood at nozzle .arms had an important imfluence on stressd concentration of nozzles.
