Abstract:For reduce the effect of airborne angle vibration on imaging quality of electro-optical pod; two small metal rubber dampers which can restrict certain degrees of freedom are developed by the application of metal rubber as the vibration isolator. The two metal rubber dampers are respectively embedded into the inner and outer frame vibration damping system of electro-optical pod, and this design of two-grade damping system realizes the three directions angular displacement vibration isolation on principle. Based on vibration theory to obtain the axial, radial stiffness and damping ratio and other parameters of two dampers and adopt special process for the preparation of metal rubber damper. The simulation analysis of electro-optical pod damper system is taken out through ADAMS/Vibration module. The analysis results show that electro-optical pod vibration inherent frequency is about 17Hz, the maximum of angular vibration amplitude is 0.0011, and when the frequency is more than 25Hz, the angular vibration amplitude approaches zero. The analysis results prove that the vibration damping system of electro-optical pod for the angular vibration more than 25Hz can be play a very good inhibitory effect. Finally, the correctness of the simulation result is verified by the vibration test. Compared with the actual measurement results, the simulation results error is less than 10%; it shows that the electro-optical pod damper design is successful. The successful application of metal rubber damper on electro-optical pod for the electro-optical pod vibration isolation technology has a very important significance.
