Design Methodology in Vehicle Dynamics, Using the Procedures of Modeling, Simulation and Analysis of System Dynamics 921480

In this paper we describe the main steps of the Vehicle Dynamics design using the generalized procedures of System Dynamics Modeling, Simulation and Analysis.

The methodology discussed is illustrated by a vehicle adaptation design, where the best kind of damper, for the passengers comfort, must be selected.

The Bond Graphs technique is used for the mathematical model development of a seven degrees of freedom vehicle, and three dampers constitutive relations are defined.

Digital simulation is employed for the vehicle behavior valuation, and we compare the roll angle for the three dampers.

Finally the analysis techniques for the optimization of the damper's selection are discussed.

The paper is concluded claiming the importance of this approach in engineering design involving high technology and complexity.
