摘要
由单点平台系泊的浮式生产储油轮的船艏结构承受着交变系泊力作用。通过详细的艏部结构有限元模型,进行了应力分析,应用S-N曲线和Miner线性疲劳累积损伤原理,进行了疲劳分析,预报了焊缝疲劳寿命。
FPSO is moored by the singlepoint platform. The bow structure bears alternate loading. Based on a loading spectrum from a shortterm prediction of the mooring force, the stress distribution in the bow structure on the basis of a detailed FE model has been calculated. SN curves and Miner rule are used for the fatigue damage assessment and prediction of fatigue life.
