摘　　要：对非常规管节点的疲劳寿命进行了分析研究,用SESAM计算疲劳载荷,应用精细有限元分析计算热点应力,用规范的S-N曲线计算管节点的疲劳寿命。通过实例计算表明,这些处理对非常规管节点疲劳寿命分析与计算是很有效的。In this paper, the research on the fatigue life of unconventional tubular joints is described. The fatigue loading was calculated though SESAM software. The hot-stress was calculated by finite element method and the analysis of the fatigue life of tubular joints was carried out though S-N curve. Finally, an example of analysis and calculation of the fatigue life of unconventional tubular joints was given to demonstrate that these methods were effective.
