热载荷作用下的结构有限元建模方法研究

INVESTIGATION OF FINITE ELEMENT MODELING METHOD UNDER THERMAL LOAD

以甲板板格为研究对象,利用MSC软件的THERMAL和STRUCTURAL模块进行建模,讨论加强筋的建模方式及单元网格密度对温度场分布、应力场分布和变形的影响。通过分析研究,对热载荷作用下的结构建模方法提出了可行性建议。

The thermal load can make the distribution of the transient temperature field of the grillage nonuniform, and create the distribution of the thermal stress field. The THERMAL and STRUCTURAL modules of MSC software are used for investigating the panel of the deck in the modeling process, and the influence of the modeling method and the mesh density of the stiffener to the distribution of the temperature field, the stress field and the ring, we give feasible suggestions displacement are discussed in this to modeling finite element module paper. After analyzing and investigaunder the thermal load.
