Abstract: Starting from the light and miniaturization design angle of optoelectronic equipment, the optoelectronic equipment vibration system was taken as the research object. According to the shortcomings of the existing built-in rubber damping system, using metal damper, a suitable external metal damping system for airborne optoelectronic equipment was designed. Through the vibration and shock test of the vibration damping system, the natural frequency, the maximum transmission rate and the maximum impact displacement were measured. Finally, by comparing the stability accuracy of optoelectronic equipment in the two kinds of vibration system, it can be concluded that the external metal damping system and built-in rubber damping system can both make the stability accuracy of the optoelectronic equipment to meet the requirements for the use of less than 25 μrad. However, the external metal damping system can improve the internal effective space of the optoelectronic equipment, at the same time, the external metal damping system as a whole replaceable unit, it reduces the maintenance difficulty of the damping system, improves the overall maintainability of the optoelectronic equipment, which is possible for the integration of other optoelectronic sensors and the realization of light and miniaturization of airborne optoelectronic equipment.
