| Abstract: | In this paper, it was realized on the personal computer that by using the test data with various confidence obtained by modal parameters identification technique, the analytical model is improved in the light of the theory of modeling according to the data with various confidence. The computational results proved that this improved method reflected the precision in the experiment more reliably. So, this method is more reasonable and may provide a more trustworthy bridge between the experimental test and the numerical analysis. |
