摘要
结构优化设计是控制生活模块总体重量、降低建造成本、缩短建造周期的有效途径。在对海洋平台直升机甲板的结构特点和受力特点进行分析的基础上,改变原来导管架平台直升机甲板H型钢桁架结构形式,把生活模块直升机甲板设计为板架式T型结构,并基于BV规范,使用MSC.Patran/Nastran软件进行有限元校核。结果表明:在满足同样载荷强度要求的情况下,采用板架式T型结构可降低直升机甲板结构重量,减少焊接建造工作量,节省建造成本,缩短建造周期。
Structure design optimization is an effective way to control the overall weight of living quarter, reduce construction cost and shorten construction cycle. Based on the analysis of the structure characteristics and force characteristics of the helicopter deck on offshore platform, the original design of H shape steel truss for the helicopter deck in the living quarter of jack-up platform is changed into T shape plate structures, and the finite element analysis according to BV rules is performed with MSC.Patran/Nastran. The result shows that the adoption of T shape plate structure can reduce the weight of helicopter deck structure on the premise of meeting same strength requirements,decrease welding work, save construction cost, and shorten the construction cycle.
