“…The vehicle's velocity in the road model is assumed to be equal to 10 m/s. This profile is a standard to simulate vertical obstacles which are used to test and set the behaviour of suspension system [16,17] and allows the behavious of suspension system to be compared. …”

The dynamic simulation of mechanical systems is an essential tool in vehicle design. This work analyses the influence of a shock absorber model on a vehicle's dynamic behaviour by means of a simulation-based model. The real behaviour of a European mediumrange car shock absorber has been obtained by means of a test rig. From the damper's real behaviour, three mathematical models were generated, increasing the complexity. An existing full vehicle simulation application (CarSim TM ) was used for this particular study. The vehicle's behaviour was analysed for typical driving manoeuvres taking into account lateral, vertical, and longitudinal forces and was compared with the results obtained with the different shock absorber models developed. As a result of this paper, it was demonstrated that, in order to obtain results with an acceptable level of accuracy, it is not necessary to rely on extremely complex shock absorber models.

This text presents a new proposal for an overall ride and handling metric to be used to optimise vehicle performance through concurrent simulation models. The proposed metric has the intention to cover simultaneously the most relevant aspects of a passenger vehicle dynamic behaviour. The individual models for ride and handling have been validated against physical measurements in order to assure a reliable output. A numerical optimisation method is used to simultaneously evaluate the complete vehicle dynamic performance related to the single overall metric. The results show an effective way to improve the vehicle performance based on this new proposed metric, with gains in terms of reduction in development time and cost for new projects.
