船体焊接结构疲劳问题的热点应力研究
Hot spot stress research of fatigue in ship′s welded structures
【摘要】 选取FPSO某一局部结构采用有限元数值计算确定热点应力 ,由此推导结构的疲劳寿命 ,将计算结果和全尺度疲劳试验结果进行对比 ,二者符合较好。
【Abstract】 Finite element analysis is carried out on a local welded structure of a FPSO to determine its hot spot stresses, and to deduce its fatigue life by hot spot stress method. The predicted fatigue life agrees well with that of the fatigue experiment of full-scale model.
