• At present, the simulation of photoelectric gimbals is only semi physical simulation, which can not meet the training requirements of full digital simulation. Based on working principle of the optoelectronic gimbals, a two-freedom-degrees optoelectronic gimbals model composed of inner ring, outer ring and bracket was built. Based on direction cosine theory and quasi Newton numerical iterative technique, for the actual equipment of the optoelectronic gimbals, the inertial work-pattern simulating & modeling algorithm (IWPSMA) were proposed in this projection, which to keep the axis stable in the inertial space. The model and IWPSMA were simulated, with the UAV moving in a circle, the azimuth changes periodically in 360°, and the elevation angle change nonlinearly in 0°-35°. The turntable model and algorithm are loaded into the 3D simulation scene. The experimental results show that the fidelity of the model and the real equipment are high, the boresight axis of the model keeps relatively stable in the inertial space, the computer resource occupation rate is low, and the 3D picture is smooth and stable.
