| Abstract: | By using finite element analysis software ABAQUS, a model analysis of a three-axis turntable was carried out, and the model′s inherent frequency and vibration type was obtained. By improving the structure of the three axis turntable, model′s inherent frequency is increased. In the end, by carrying out random response analysis of the model, the acceleration curves of a node in the model are output. These data and curves can support vibration experiment of three axis turntable. |
