On the numerical solution of a wheel suspension benchmark problem

For the simulation of a five-link wheel suspension, an alternative formulation with built-in projection and corresponding numerical algorithms are presented. The wheel suspension, a bechmark problem in vehicle dynamics, can only be modeled as a system of differential-algebraic equations (DAEs). Besides the numerical integration, the computation of consistent initial values and the treatment of discontinuities play an important role. Simulation results illustrate the performance of the introduced algorithms.
