In this paper, by compared with the frequency and vibration mode with test results, set up different weight coefficient, a finite element model of a comprehensive evaluation method have been proposed. With this method, designed the dynamic programming based on MATLAB programming, and call the finite element software of Nastran, The program can use the powerful computing capacity of MATLAB and Nstran, a series of work can be do, such as matrix extract, freedom match and model evaluation. The procedure is simple and reliable results, it can be used to obtain the finite element model structure information, and can be quickly applied to engineering practice.
