The Modal Analysis for Some Platform
The modal analysis for the platform is a necessary means to keep in good condition and to improve the structure. The hardware structure is given in this paper. The method for modal analysis is also given out, which is based on trigonometric polynomial fitting. The former three rank inherent frequency as the result of the modal analysis is calculated out. In the conclusion, the shortcoming is given and the solution is put forward.
