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.
