Based on two application examples, i.e. a DCactuator and a brake pedal system, the analysis of this article demonstrates, which synergies can be achieved by applying system simulation.The first example, focussing on the simulation of the temperature behaviour of a DCactuator to identy critical operating conditions, reveals an effort reduction by a factor of 4 in comparison to measurements.The second example, a brake pedal system, shows an approach of contact modeling between rigid bodies in Modelica, in order to analyse the kinematic movement of the pedal and its force-path characteristics.In this case, the original effort of model creation has been reduced by a factor of 10 s.Beside the increase of efficiency, the respective de-sign concepts could be optimized concerning the friction and temperature behaviour according to the specifications.
