子结构分析的基本原理和ANSYS软件的子结构分析方法

目前子结构的理论日趋成熟完善，并且已经广泛用于结构分析计算，但是具体操作的论述较少，初学者要掌握这一高级的分析方法并非易事．针对这种现况，本文首先介绍了予结构的基本原理，然后简述美国SASI公司开发的ANSYS软件子结构的分析方法的基本步骤，并通过一个实例演示分析过程．为了进一步加深认识与提高子结构的分析水平，又对一个特殊横梁刚架作了予结构的分析论述，有力地说明了该方法的高效性．

The basic principle of substructure analysis and the technique of substructure analysis with the software of ANSYS

At present, the theories of substructure analysis are more and more perfect gradually, and already extensively used for the structural analysis compute, but there are less specific thesises about the concrete operation.It is not a easy thing for the beginners to master the advanced analysis method. Based on this current conditions,here,The authors introduces the basic principle of substructure analysis at first,then present the basic steps of substructure analysis in the software of ANSYS in a simple way and particularize a solid example to show the process.In order to understand better and enhance the level of substructure analysis,the authors demonstrates the process of a special beam's substructure analysis.Also,the example strongly prove the high efficiency for the foregoing technique.
