Simulation has established itself as an essential tool in the virtual chassis development process to reduce both development time and costs, especially for suspension design. In the literature, a variety of characteristic values are proposed to characterize and benchmark suspension systems. These characteristic values play a vital role for the design of suspension kinematics and compliance. This paper presents an approach for the analysis and characterization of suspension systems within multi-body simulation, which makes use of the suspension system’s compliance matrix. A universal methodology for the calculation of the existing characteristic values, which characterize both steering feedback and wheel guidance, by means of the compliance matrix is outlined as well. The results demonstrate the application of the proposed approach to several exemplary use cases within suspension design. The newly gained insights with this method can be used to further enhance suspension design by improving the characterization and benchmarking of suspension systems.
