This study is focused on development of an integrated elevation and azimuth dynamics of an electrically driven weapon platform. Initially, the elevation dynamics of the weapon system, driven by an electric drive consisting of 5 degrees of freedom, is developed. The azimuth drive of the weapon dynamics, governed by turret rotation, is subsequently incorporated in the same model. The weapon dynamics math model has been integrated with a 17 degree of freedom ride math model of a 14-stationed tracked vehicle. Ride mathematical model will be subjected to road excitation such as Aberdeen Proven Ground (APG) input. Predetermined torque input to aim the main gun at desired location, as well as outputs obtained from the ride math model, such as bounce, pitch and roll of the sprung mass (hull) is given to elevation and azimuth drive. Modelling and development is done in SIMULINK environment for fixed time step, simulating weapon dynamics, coupled with the drives, using a lumped parameter beam for modelling the gun. Passive responses given by the main gun barrel at breech and muzzle CG are measured. The responses obtained from the SIMULINK math model, are validated by simulating the stand-alone model developed in ADAMS for elevation and azimuth dynamics. The integrated dynamics math model would provide a very useful platform for implementing the desired control system to stabilize the weapon platform in an operational dynamic environment and it improve upon the first-round hit probability.
