This research presents modeling techniques of a stabilized remote controlled weapon system on the naval ship using multi-physics simulation. Multibody model, aero-hydro force interaction, and control interface are incorporated with each other. In order to verify the stabilization of orientation of remote controlled weapon system, the results from the dynamic model incorporated with MATLAB/Simulink are compared with the results from actual 6-DOF motion simulator. A shock absorber of the gun is essential of reducing the fire shock and dynamic model of shock absorber is characterized by the stiffness and damping constants. In order to obtain the actual damping and stiffness constants, a vibration experiment for the shock absorber of the gun is performed. In order to make the dynamic model of a naval ship enable to float on the sea, aero-hydro force elements are used. Also a wave force modeling technique is proposed in order to simulate wave motions in the sea.
