摘要
以某型自升平台的桁架式桩腿为研究对象,建立了桩腿疲劳分析简化模型,采用谱疲劳分析方法并结合Palmgren-Miner线性疲劳累积损伤理论和API推荐的S-N曲线,实现对自升平台桁架式桩腿疲劳寿命预测,为此类结构设计人员提供参考。
Taking the truss leg of a Jack-up for example, a simplified fatigue analysis model for the leg is established. Then the fatigue life of the leg is predicted by using spectral fatigue analysis method, combining with Palmgren-Miner linear accumulative damage theory and S-N curves recommended by API. The method in this paper can be referenced by such structure designers.
