Abstract

Various simulation models are used extensively for the design and the optimisation of vehicle suspension systems, as well as the application of various control algorithms in them. The selection of the most suitable model for these purposes is never explained and many times unnecessary complexity is added in them. In this respect, an assessment regarding the accuracy of the most common vehicle models is conducted. Thus, four vehicle models with various configurations are compared in terms of accuracy. More specifically, both passive and semi active suspensions are employed to the models, while the effect of adding anti-roll bars and tire dampers is also investigated. The transient behaviour of the suspension system and the overall vehicle performance are assessed in terms of ride comfort, vehicle handling and road holding using different road excitations. The results illustrate the ability of lower accuracy models to cope well and that they should be preferred most of the times. Also, anti-roll bars and tire dampers should be neglected when the ride comfort is investigated, whereas they have to be included when simulations regarding road holding are conducted.
