自升式平台悬臂梁及相关结构设计研究

Design of cantilever beam at jack-up platform and related structures

为了降低悬臂设计周期,快速评估悬臂梁的强度,通过对自升式平台悬臂梁结构特点及工作状况的分析,运用数学模型法和有限元方法对不同工况的悬臂梁结构进行强度评估。根据国际船级社规范要求,对设计结构进行有限元强度分析,并确定了悬臂梁结构的安全可靠性。

In order to reduce the period of cantilever beam design and calculate its strength in a short time,the structural characteristics and the working status of cantilever beam at jack-up platform were analyzed firstly,then the strength of cantilever beam was evaluated by numerical model and finite element method. And then the structure design was analyzed by the finite element method according to the international classification society code,thereby the safety and reliability of the structure of cantilever beam was ascertained.
