In order to observe the dynamic processing of missile launching by a optoelectronic pod, an inner frame vibration absorbing system for the optoelectronic pod was developed. Firstly, the working environments and working principles of the pod were analyzed, and the necessity to damp the vibration of inner frame was pointed out. The characteristics of vibration absorbing systems were discussed and how to eliminate the shaft gas was given. A module driving shaft was designed, which combined the thicknesses of torque motor and bearings to decrease the shafting space and to increase the space of effective load. Finally, an inner frame vibration absorbing system was designed. By module combination, the system is more flexible and universal. Furthermore, by using the independent appliance and carrying horizontally forward the inner frame into the outside frame, the system is easy to assemble and adjust greatly. A vibration experiment on the optoelectronic pod with an inner frame vibration absorbing system was carried out in a test field and a simulated target was also observed, obtained results indicate that the pod has a good working condition and the video image of target is clear and fluid. The tracking experiment shows that the tracking error is less than 1 mrad.
