The use of main battle tanks in armies goes back many years. The most crucial
component is undoubtedly the weapon system. In this study, it is aimed to model the
elevation dynamics of the weapon system that provides the movement of the weapon
system in the vertical axis. The elevation dynamics consists of three parts: an electric
motor, a driver, and a barrel. The barrel consists of two parts, a breech section and a
muzzle section. Both parts are expected to have similar vibration characteristics. The
linear graph method was preferred as the modeling method. First of all, the system
components and types were determined, and the linear graph, normal tree, and tree
links of the system were drawn. Then the state variables, primary and secondary
variables, as well as the number of branches, nodes, and sources, were determined
respectively. Elemental, continuity, and compatibility equations were written using the
obtained graphs. By organizing these equations, state equations were obtained in
standard form and matrix form. With the simulation studies carried out in
Matlab/Simulink, the displacement, velocity, and acceleration responses of the breech
and muzzle sections were obtained. When the obtained graphs were analyzed by
considering the maximum and root mean square (RMS) values, it was observed that
the breech and muzzle sections had similar vibration motions
