摘要
基于渤海湾浅海海洋平台在动力荷载作用下的动态响应进行分析,建立合理的海洋平台有限元模型。根据我国海洋平台相关规范及渤海湾环境条件选择相应的荷载计算理论,分析海洋平台在环境荷载工况下的受力情况。利用有限元软件模拟海洋平台结构,通过APDL语言分析海洋平台在环境荷载作用下的动力响应;通过有限元软件的可靠度分析模块,对海洋平台可靠度进行分析。
Based on the dynamic response analysis under the environmental loads of offshore platform in Bohai Bay,the rational finite element model for offshore platforms is established.Appropriate load calculation theory which according to relevant regulations of offshore platform and the environmental conditions in Bohai Bay are selected to analyze the forces of offshore platforms in a variety of load conditions.Analysis the dynamic response in a variety of load conditions by the language of APDL,and the reliability analysis of offshore platform are carried on by the reliability module of the FEM software.
