The article provides a discussion on oscillatory methods used for technical condition assessment of shock absorbers in automotive vehicles, focusing primarily on free vibration methods. It comments on results of simulation studies of a simple two-mass model conducted by application of a pulse input function. Results of experimental tests have also been provided in the paper. The foregoing tests consisted in recording of accelerations of the body of an automotive vehicle equipped with a shock absorber enabling simulation of shock absorbing liquid leakage. The follow-up analyses were conducted to establish the decrement of damping as well as the damping coefficient.

W artykule opisano metody drganiowe stosowane w ocenie stanu technicznego zawieszenia pojazdu samochodowego ze szczególnym uwzględnieniem metody drgań swobodnych. Przedstawiono wyniki badań symulacyjnych dla prostego modelu dwumasowego przy wykorzystaniu wymuszenia impulsowego. Zaprezentowano również wyniki badań eksperymentalnych. Badania te polegały na rejestracji przyśpieszeń drgań nadwozia pojazdu samochodowego wyposażonego w amortyzator umożliwiający zasymulowanie wycieku płynu amortyzatorowego. W ramach analiz wyznaczono dekrement tłumienia oraz współczynnik tłumienia.
