Influence of inertia moment of infantry fighting vehicle turret on accuracy of aiming at a target and tracking of a target

In the paper was tested one of combat vehicles that is highly dynamic military vehicles, combining a high striking and fire power with high mobility and manoeuvrability. Were presented the mechanism of transfer of disturbance from the ground on the angular stabilized turret of the vehicle. Hull vibration caused by bumps in the ground. Angular and axial displacement of vehicle are the input signals acting on the turret and the gun. Two-axis stabilisation system compensates the velocities of the vehicle. Stabilisation system, automatically maintain the position of the turret at a fixed bearing in space. In spate of any motion of the vehicle in roll (hall transversal vibration) or in yaw (hall "snake-like" vibration). Torques and forces acting on the rigid body of combat vehicle turret are written in equations of motion. To examine the effect of mass inertia moment of the IFV turret on the size of first overshoot (to confirm the theoretical considerations) performed a simple experiment. Was measured the size of the angle of the first overshoot of the turret when braking rotating turret with a maximum angular velocity. Measurements were made on the IFV turret in the previously existing configuration, and when mounted on it extra weight. An experiment confirms the theoretical considerations. The results of measurements show that an increase of approximately 8 per cent of the mass moment of inertia of the turret causes about 16 per cent increase in the amplitude of the first overshoot.
