The paper focuses on the influence of the longitudinal and lateral suspension damping in correlation with the velocity upon the vibration behaviour of the railway vehicles while moving on a tangent track. The numerical simulations are developed based on a linear model of a 17-degree of freedom vehicle that allows the evaluation of the dynamic behaviour of the vehicle in a sub-critical velocity. Based on the response frequency functions of the vehicle in a harmonic and in a random behaviour, a series of basic properties of the stable behaviour of the forced lateral vibrations has been made evident, as well as the opportunities to lower the level of the carbody vibrations by changing the suspension damping.

W artykule skoncentrowano się na wpływie, jaki tłumienie wzdłużne i poprzeczne w zawieszeniu, w połączeniu z prędkością, ma na właściwości drgań pojazdów szynowych poruszających się po torze prostym. W oparciu o model pojazdu o 17 stopniach swobody opracowano symulacje numeryczne, które pozwalają na ewaluacje właściwości dynamicznych pojazdu w zakresie prędkości podkrytycznych. Na podstawie funkcji odpowiedzi częstotliwościowych dla drgań harmonicznych i przypadkowych wyznaczono szereg podstawowych właściwości stabilnego zachowania się pojazdu w warunkach wymuszonych drgań poprzecznych. Pokazano też możliwości obniżenia poziomu drgań karoserii przez zmianę tłumienia w zawieszeniu.
