The lightweight design of the inner framework of the opto-electronic stabilization platform based on finite element analysis

The airborne opto-electronic stabilization platform should have the characteristics of high requirements for stability, tracking accuracy and lightweight. In order to verify the rationality of the main load-bearing structure, the inner-gimbal, finite element analysis was performed. Because of the poor working conditions of the airborne opto-electronic stabilization platform and the wide range of working temperature variation, -45 °C ~ 60 °C, according to the actual working environment, air-resistance and temperature were added to the loads of the inner-gimbal in analysis. What´s more, based on the analysis results, lightweight design was performed to the initial model and 64.37% of mass was decreased. The remarkable effect was obtained. This research is going to be instructive to design and production of the airborne opto-electronic stabilization platform in the future.
