The multibody system approach is used for the investigation of mechanical systems with large motions, e.g. in vehicle dynamics and robotics. Important modules of a computer-aided tool proposed for analysis and optimization are filtering techniques and scalar optimization algorithms. Formfilters are used for the creation of stochastic exciations and criterion computations.
Typical properties of deterministic and stochastic scalar optimization algorithms with application to dynamic systems are presented and a hybrid deterministic-stochastic approach is proposed which combines the advantages of both algorithm types. An application to vehicle dynamics clarifies the optimization concept.
