In order to effectively improve the servo control of the high-speed ball screw feeding system, an identification method for the rigid body and vibration of the feeding system was proposed, and the highspeed ball screw feeding experiment platform was established.The fundamental parameters of the system were obtained by means of time-domain and frequency-domain identification, the moment of inertia, damping and Coulomb friction of the experimental platform were identified by using augmented least square method, and the friction model was determined by using Kalman filter.The frequency response function of the system was obtained by using sinusoidal sweep frequency identification method, and the axial torsional vibration transfer function and the frequency response function of the experimental platform were obtained by using peak value method and the least square method.The influence of different position and mass on the vibration characteristic of the system was tested through experimentation.The accuracy of the identified transfer function and frequency response function was verified by comparing with the experimental value.
