Co-simulation modeling and performance prediction on bidirectional stability system of gunner's sight

This paper initially analyzes in detail the control principle of bidirectional stabilization system for vehicular gunner's sights, derives the mathematical model of the system based on the inertial stabilization principle. On this basis, a collaborative simulation model for the bidirectional stabilization system of the gunner's sight was constructed by using RecurDyn and Matlab. Secondly, in order to verify model accuracy, stability accuracy was used as the evaluation index, and the model was adopted to simulate the stability accuracy test of the gunner's sight mount. The simulation results were compared with the actual mount test results, indicating a model accuracy of 83.2% compared to actual test results. Finally, to evaluate the practical application effect of this gunner's sight on tracked vehicles, the natural road spectrum curve of tracked vehicles traveling at 30 km/h was applied as the disturbance input for the model. The collaborative simulation model could be utilized to predict the stability performance of the bidirectional stabilization system for the gunner's sight during vehicle movement.
