Abstract
In this study,we propose high performance and high reliability analysis method for eigen problem of the system with large degree of freedom.Analysis method is composed by applying transfer stiflhess coefficient method to the inverse iteration method.With respect to the inverse iteration method,the iteration process is regarded as the forced vibration analysis of large scale linear system.To this process,we apply transfer stiflhess coefficient method,which is able to compute the vibration solution of linear system at high-speed.By this combination,computational efficiency and computational accuracy can be dramatically improved.In this report,we apply this method to an eigen problem of a three-dimensional beam structure.We investigate the effectiveness of the proposed method by comparing analysis results of this method and conventional method.
