| Abstract: | Based on the study of the previous comprehensive application of finite element analysis method and experimental modal analysis technique,the time domain mathematical model of correlation analysis for the responses of the experiment and the corresponding finite element model is established with the time series analysis theory.The correctness and feasibility of the analysis theory proposed in this paper is verified by the correlation analysis of the clamped beam and the lidless bucket which is fixed at its bottom.As a result,we provide an applicable and simple analysis method of the applied correlation determination of the finite element model and its modification. |
