Structure design and implementation of a two-axis four-gimbal electro-optical pod

Abstract

Abstract Multi-load, high stability and precision optoelectronic pods have become the development trend of pod technology applications. The two-axis four-gimbal electro-optical pod has the characteristics of high integration and stability. The research object of this project is a two-axis four-frame optoelectronic pod carried by helicopter. It can realize the transmission of active video and measurement control data through an airborne data chain. The system composition of the pod was introduced, and a mechanical structure model was established. To ensure rotational performance, a method for calculating the torque of the motor was provided, simulation of a main load-bearing structural part was conducted to ensure the structural strength. Finally, the stable accuracy was verified through testing. Design and analysis methods can provide some references for the design of two-axis four-frame pods.
