An effective vibration isolation design is of necessity for ensuring the stability and track precisions of Airborne Opti-electronic Platform(AOP), and decreasing the effect of vibration disturbance on the optic payload system on AOP. Such a design for AOP of a UAV is indicated according to passive vibration isolation theory and dynamic model, and the isolation effect is illustrated with a vibration test. The test results show that RMS the acceleration of the interior measuring point of the vibration system is 60% less than that of exterior measuring point. It proves that the feasibility of the design is reasonable, and the practice and analysis are helpful to further design optimization.
