| 摘 要： | 本文运用有限元方法对海洋石油钻井平台中采用内圆环加强的 T 型管柱接头进行了系列计算和分析。研究了各种载荷工况下不同加强形式的内圆环对降低热点应力的效果和规律,并提出了以加强圆环、主管壳板及支管壳板三者之间的相对刚度系数 K 为参数的计算单圆环加强的 T 型管柱接头热点应力集中系数的方法。

| Abstract: | In this paper,finite element method is applied to a Series of calcula-tion and analysis of T-joints With internal ring stiffeners for offshoredrilling platform.The effect and regularity of ring stiffeners with differentconfiguration for reducing hot stress under different loading conditions arestudied.On the basis of finit element analysis a SCF calculation methodfor T-joint with single ring stiffener is proposed,using K,which is therelative stiffness factor among chord,branch and ring,as parameter. |
