Abstract
The method of time series analysis is one of the most important time domain modal analysis techniques, however, its application to automotive experimental modal analysis is restricted by lack of an effective way to determine order of the time series model, By G-transformation, a new criterion for determination of model order is presented in this paper, so the obstacle is overcome. Besides, a new algorithm for estimation of time series model is presented and two kinds of models are used for identification of modal parameters, therefore the method of time series analysis can be applied better to automotive modal analysis. Last, an example of identifying automobile frame by our method is given. The identification results are better in conformity with the results of frequency domain method.
