将导管架海洋平台看作空间钢架结构,环境载荷考虑随机波浪作用并在频域上进行处理,应用ANSYS软件对导管架平台进行PSD动力学分析,得到结构的动力响应参数,应用谱分析方法对导管架平台管节点进行疲劳分析与寿命估算。并以位于渤海湾的CII海洋平台为例进行了计算,说明该方法的实用性与简便性。
Abstract：A jacket platform was modeled as a steel frame structure under irregular wave loadings in the fre- quency domain.The FEM software ANSYS was applied to study the dynamic characteristics of the structure using the PSD analysis method.With the responses of the platform,a fatigue analysis by the spectrum method was carried out on the structure and the life of the platform was estimated.As an example,the CII Offshore Platform located in Bohai Bay was simulated.The proposed method is proved to be practicable.
