This paper presents a dynamic simulation study of a passenger car. The passenger car is equipped with a standard Polish bogie 25ANa. The bogie 25ANa has been designed by Ryszard Suwalski [1]. Spectral analyzes performed to detect damage to the vehicle suspension. In studies used a multi-body, dynamic calculation system SIMPACK 9.5. All analysis presented here are based on the standard wheel-rail profile combination S1002/UIC60, the rail inclination 1/40. The accelerations from the dynamic simulation used to calculate and create spectral markers. Spectra calculated using the Fourier transform.
