Fast motion of piezoelectric turntable is an important guarantee for fast target locking and tracking of imaging system. Vibration of piezoelectric turntable in fast motion will seriously affect imaging quality and even damage imaging system. Therefore, the three-dimensional model of high-speed small piezoelectric turntable is built by SolidWorks software, and the finite element model is established by ANSYS software to analyze the dynamic characteristics of the piezoelectric turntable. The natural frequencies and modal modes of the turntable are obtained by modal analysis. On this basis, the harmonic response analysis is carried out, and the amplitude-frequency characteristic curve of the piezoelectric platform is obtained. The analysis results show that the dynamic characteristics of the designed high-speed small piezoelectric turntable meet the design requirements, and there will be no resonance.
