Abstract:

The dynamic behaviour of a vehicle has been studied with the aim of investigating vehicle ride comfort. For ride behavior a quarter vehicle model has been developed to study preferred suspension properties. The passive suspension system used consists of a non-linear damper and coil spring. A non-linear damper model has been developed. This model with bush end stiffness and asymmetric damper model was implemented into the vehicle model, and is used for analysis and optimization of suspension ride behavior. The ratio between damping coefficient in rebound and compression is discussed. Also, the ride performance of the damper model is evaluated and the results are discussed. A quarter vehicle test rig is used to evaluate the vehicle ride performance. One damping parameter was used, and the results were compared with those obtained theoretically. The results showed that the damper has a great influence on the vehicle ride characteristics. The experimental and theoretical results were found to be in a good agreement.
