摘要
对接管轴向推力作用下圆筒形压力容器开孔－接管高应变区的变形及局部应力进行试验研究。针对３台具有不同ｄ／Ｄ比值的试验容器进行这项研究工作。结果表明，其应力和变形具有明显的局部性，最大应力出现在容器横向截面上（０＝９０℃），并将本文所得的结果与ＷＲＣ．１０７及ＷＲＣ．２９７进行了比较。
篢he results of verification of the deformation and stress behavior in the vicinity of cylin-der-nozzle intersection are presented，when the nozzle is sujected to an axial thrust load．A detailed experimental study was catried out for three test vessels with different d/D ratios.The results indicate that stresses and deformation possess obvious localized behavior and that the maximum stress in the ves-sels occurs in the transverse section（θ＝ 90°）of the vessels．A comparison between the restults of pre-sent study and those from WRC. 107 and WRC. 297 were also given.
