Abstract

For airborne optoelectronic platform with two axes and four frames, the dynamic model of vibration reduction system is established. Simulation analysis and experimental test for vibration reduction system are made under the condition of stiffness perturbation and barycenter perturbation respectively. Simulation results show that linear vibration accounts for angular disturbance when stiffness perturbation or barycenter perturbation exists. Angular disturbance error is 25μrad and 34.28μrad when barycenter perturbation is 1mm and stiffness perturbation is 1% respectively. Vibration experimental test results show that coupling exists in combination of two kinds of damping system. Angular disturbance coupling of damping system becomes less when stiffness perturbation and barycenter perturbation are reduced. The method provides a new train of thoughts for making a reasonable configuration on stabilized platform damping system.
