Analysis of the XM97 Turret Dynamics with Active Servo Control

Abstract

A method of analysis has been developed for investigating the dynamic motion of a gun-turret configuration. The analysis allows for elastic coupling between the three main components of the turret and for active servo control system which is also coupled with the turret dynamics. The three main components of the turret are the stationary ring, the rotating ring, and the saddle-gun assembly. The gear systems in the azimuth and the elevation drives are characterized by their gear ratio, elastic stiffness and frictional coefficient. The dynamic equations which govern the motion of the system are reduced to five first order equations which are solved numerically. The forces which cause the system to vibrate are generated by the helicopter structural vibration and by the torques produced by the recoil forces. The helicopter vibration effects are obtained by coupling this analysis with the finite-element analysis of the helicopter structural model. A computer program has been prepared to solve the governing equations.
