【摘要】 通过数值分析得到承受轴向力的TT节点在热应力区的应力分布以及最大应力集中系数,并通过计算发现TT节点在两个支管均承受拉力作用的时候,最大应力集中系数位于两支管相邻的鞍点处。在此基础上,通过对不同几何参数的TT节点进行的模型分析,得到TT节点的几何参数对应力集中系数的影响。更多还原

【Abstract】 The stress distribution and the peak stress concentration factor in the hot spot stress region for tubular TT-joints subjected to axial loads have been analyzed in this paper. Through numerical analysis, it has been found that the peak stress concentration factor is located at the saddle position which is near the gap between the two braces when a TT-joint is subjected to tensions at the ends of both braces. Thereafter, the effect of the geometric parameters of a TT-joint on the stress concentration factor result has also been investigated through analyzing numerical models with different geometric parameters.更多还原
