基于线性和非线性波浪理论,在渤海海域观测的30种海况下,选取了导管架平台易发生疲劳损伤的几个危险节点作为研究对象,并通过确定性的疲劳分析方法对这些节点进行了疲劳寿命评估。结果表明,在选取的3种阻尼条件下,考虑波浪的非线性因素后,疲劳寿命的评估结果均有所增加,为海工结构的疲劳寿命评估提供了参考意见。
Based on the linear and nonlinear wave theory, under the 30 sea-states observed in the Bohai Sea, several dangerous nodes prone to fatigue damage on the jacket platform are selected as the research objects, and the nodes are subjected to fatigue through deterministic fatigue analysis Life assessment. The results show that the fatigue life assessment results are all increased under the selected three kinds of damping conditions considering the nonlinear factors of wave, which provide reference for the estimation of fatigue life of marine structures.
