摘要
本文对船用锅炉汽水联箱进行了热弹塑性应力场非线性有限元分析，绘出了其三维应力分布图及变形图，并对应力集中的局部区域进行了二次有限元计算。计算结果对分析联箱内部损伤有重要价值。
In this paper, the thermo-elastic-plastic field of a marine boiler drum is analyzed by using FEM, and diagrams of three-dimensional stress and deformation are given. The finite element calculation was carried out at twice for the region of stress concentration. The numerical results are of significance for analyzing the damages of boiler drum.
