Аннотация:The paper presents a computational experimental comparison of the dynamic characteristics of a fragment of a model body of an armored personnelcarrier. The method of experimental research was to determine the dynamic response from the action of a shock load by a rubberized drummer. Theresults were recorded with a 795M vibration spectrum analyzer using an acceleration sensor DN-3-M1. Numerical studies are performed in the moduleof transient dynamic analysis. For the obtained dependencies, the Fourier transform is constructed. A separate stage of computational and experimentalstudies was performed varying the mass of the combat module. It is determined that the results obtained by the experimental method are in goodagreement with the similar results obtained by calculation methods. The comparison was performed for accelerations, velocities and displacements atcontrol points and for Fourier transform also. The influence of tower mass on the natural oscillations spectrum was also analyzed in the work. Studieshave shown that increasing of tower mass reduces the system's natural frequency
