摘要	In order to realize precise control of photoelectric turntable, the dynamic characteristics of the vertical shaft of a type of photoelectric turntable are investigated. First, the relationship between the natural frequency of the shaft and the turntable is analyzed, and the dynamic model of the vertical shaft is built. Then, the finite element model is established, modal analysis is carried out and the excitation and boundary conditions are loaded according to the actual working conditions. Using explicit integration, the response of the turntable is solved. Finally, the experimental platform for researching the dynamic characteristics of the vertical shaft is set up. Servo scanning experiment is carried out to obtain the characteristics of the shaft in time domain and frequency domain. Results show that the natural frequency obtained by kinetic analysis is 180.4 Hz, by simulation is 190 Hz and the experiment result is 174 Hz, the maximum error is less than 10%. According to the analysis, a reference scheme to increase the natural frequency of the vertical shaft system and to select the control bandwidth is proposed. This scheme provides the reference for research on the dynamic characteristics and optimization of the shaft system. 2018, Editorial Board of Jilin University. All right reserved.
