为实现对大型LNG船集管区平台的高效与高质量设计，提出一种集管区平台的三维参数化设计方法，通过CATIA V6软件二次开发和知识工程模板，快速搭建平台的有限元模型和实体模型，并实现工程图出图；同时提出一种对大型LNG船集管区平台的加载方式，利用有限元数值仿真技术对平台的强度进行计算校核。研究表明，采用该参数化设计方法较常规设计周期缩短了8天，提高了设计精度，加载方式可有效模拟平台的受力情况，为今后同类LNG集管区平台的设计提供一定参考。
In order to realize efficient and high quality design of large LNG carrier manifold platforms, a three-dimensional parametric design method of large LNG carrier manifold platform was proposed. The finite element model and solid model of manifold platform were quickly built through CATIA V6 software secondary development and knowledge template, and engineering drawing was realized. At the same time, a loading method for large LNG carrier manifold platform was proposed, the strength of manifold platform was calculated and checked by using finite element numerical simulation technology. The research shows that the parametric design method can effectively shorten design period and improve design accuracy. The loading method can effectively simulate the stress of manifold platform, which provides a certain reference for the design of similar LNG carrier manifold platforms in the future.
