子模型技术及其在焊接十字接头应力分布分析中的应用

Submodeling technique and its practice in the study on stress direction of cross joint with the welds transverse

在使用有限元法进行结构分析中,针对整体结构进行的有限单元的划分,其精度无法满足局部结构分析的要求,子模型技术很好地解决了这一问题。介绍了ANSYS软件中子模型技术的概念、适用场合及具体的操作过程,并运用此技术于焊接十字接头应力分布的分析中,作出了应力分布曲线。

Often in finite element analysis, the finite element mesh may produce satisfactory results to whole cortstruction but not to a region of interest, Submodeling technique can be used to solve this problem . Introduced this method and use it in the study on stress direction of cross joint with the welds transverse.
