Modeling and analysis of a twin-tube hydraulic shock absorber

Urszula Ferdek, Jan Łuczko
In this paper, a physical and mathematical model was created for a twin-tube hydraulic shock absorber, using oil as the working medium. To analyze the model, methods of numerical integration were incorporated. The effect of the amplitude and frequency of the excitation, as well as the parameters describing the flow rate of oil through the valves, were examined. The basic characteristics of the damping force were obtained.
