In order to provide reliable data for the dynamic design or modification of a tool machine, the dynamic characteristics of the headstock, which is the main component to bear moment, must be obtained precisely. In the paper, the method based on the combination of calculation mode and experiment mode is proposed to analyze the dynamic characteristics of the headstock. The modal parameters and the mode shapes are calculated by ANSYS7.1 software. According to the FEM calculating results, the experiment parameters can be selected correctly. The modal parameters of the headstock have to be calculated and identified precisely. On the basis of these modal parameters, the faults of the headstock are shown and its weak points of design are illustrated. A conclusion is drawn that some reasonable reinforce positions could greatly improve the dynamic characteristics of the system and this approach is proved to be precise and reliable.
