Opto-electric scouting & tracking device is used to scouting the object of hemisphere airspace and tracing of movement tail of object in real time. The precision turntable was important parts of scouting device and it was crucial to the scouting device's technology guideline, such as tracking precision, scouting range, volume and quality etc. To achieving the purpose which scouting & tracking device's volume smallness, quality light, rigid bigness and precision highness characteristics, the mechanical structure of turntable was designed in this paper. Then, the static and dynamic analysis of the precision turntable frame was done using the finite element method. The static analysis results show the intensity and rigid requirement of tracking turntable frame was satisfied, and it had big space to reducing. So the structure optimization design can be done to reduce the frame's volume and moment of inertia. The optimization design of turntable frame was done based on the establishing the optimizing mathematics model. The objective function of optimization was minimizing frame volume. The optimizing result indicated the optimizing effect was distinct. The volume of precision opto-electronic tracking turntable frame reduced 15%. The intensity and rigid of precision opto-electronic tracking turntable frame were verified after optimization, the results was satisfied to the design requirement. It provided important reference to improving the Opto-electronic scouting and tracking device.
