N2 - This research focuses on the study of the influence of asymmetrical characteristics of damping force on the ride quality of a typical passenger car. With different standard road inputs, variation of severity parameter, asymmetry ratios, asymetry average as well as the velocity of the vehicle, performance indices and root mean square (RMS) values of acceleration of the sprung mass in respect to vehicle velocity are derived so that the efficacy of the asymmetrical systems can be assessed. The comparison between the symmetrical and asymmetrical systems subjected to the modified bump inputs showed that the asymmetrical system, with nonlinear characteristics and asymmetry ratio above 1, tends to have a smoother and more progressive performance. The comparison between the symmetrical and asymmetrical systems subjected to harmonic inputs showed that the asymmetry ratio of the systems does not influence the performance, instead the asymmetry average does.
