摘要
介绍了海洋平台结构整体疲劳寿命预测的方法与步聚 ,给出了平台构件等效疲劳应力幅的简化计算方法和预测疲劳寿命的模型 ,并以渤海八号固定采油平台为例 ,对平台整体疲劳寿命进行了预测与分析。
The prediction method and step of fatigue life of whole offshore platform are introduced.The simple calculation method of equivalent fatigue stress range and the model of fatigue life prediction of structure members are given.The paper also takes the No.8 Bohai fixed production platform for example to carry out the prediction and analysis of fatigue life of whole platform.
