System Simulation as Part of Systems Engineering for Headlamp and Pedal Systems based on the Modeling Language Modelica

. Based on two application examples, i.e. a DC-actuator 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 DC-actuator 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.
