Abstract

Various mathematical models, also known as lumped parameter models, have been employed for studying vehicle dynamics. In the present study, the responses of different models are studied and compared for different road conditions. The mathematical models considered are: (i) a two degrees-of-freedom system (quarter carmodel), (ii) a four degrees-of-freedom system half car model) and (iii) a seven degrees-of-freedom system (full car model). These systems are analyzed using SIMULINK®for pitch and roll modes of inputs. Various response parameters such as body acceleration and body displacement are obtained using representative passive suspension system properties. The current study aims at evaluating the capabilities of different modeling approaches mentioned above and their de ciencies
