摘要
试油船燃烧臂的结构设计通常采用船用吊机的设计方法,所设计的结构过于保守,使得结构质量偏大。文章通过数值模拟,针对不同的工况,计算了胜利油田海运九号石油工程船燃烧臂结构的应力与变形,分析了燃烧臂各部分的最大弯曲应力。对燃烧臂底座进行了弯曲强度、剪切强度及抗挤压强度的校核。计算结果可以对燃烧臂及其底座的设计与优化提供重要的参考依据。
The combustion beam structure of oil ship is usually designed according to the rule of marine crane. And this is too conservative and it will make the weight of the structure too heavy. The stress and deformation of the structure are calculated by numerical simulation. The maximum stress of each part of the structure is obtained. And finally, the strength of bending, shearing and extruding is checked. The results can give useful information for the designing and optimizing of the combustion beam structure.
