Paper Abstract

The vibration environment of the internal opto-machinal system of the electro-optical pod is different from the external vibration environment and needs to be accurately defined. Based on the detailed analysis of the vibration source distribution and response bandwidth of the airborne electro-optical system, the Cassegrain Opto-mechanical System is taken as the research object, and the complete analysis process is established from the original environmental excitation. The equivalent vibration algorithm is used to determine the micro-vibration conditions. The finite element detail model of the connection method is used for dynamic response. At the same time, based on the simulation model optomechanical system, an optical axis drift analysis method based on feature point correlation and response extremum judgment is proposed. The relationship between the displacement mode and the amount of drift of the optical axis is obtained.
