Using System-Level Simulation in Early Mechatronic Design Stages

Simulation has become indispensable in engineering design. That is the reason why the authors developed a framework for simulation-based design of mechatronic systems where system simulation is intended to be used already very early in the design process. Besides the benefits in early phases, there are several issues caused by unknown or vague system parameters required for simulation. Such uncertainties lead either to models which cannot be simulated or to deficient simulation results. In this paper the different reasons for and the origins of uncertainties as well as the related deficiencies of simulations will be analyzed and discussed. Furthermore the state of the art is analyzed regarding existing methods and techniques for the improvement of reliability and results of simulation. In order to improve the usability and reliability of simulation in early phases the analyzed techniques are integrated into the simulation-based framework and validated on a mechatronic design example.
