In contrast to Robust Design applications for FEM-modeled parts, the simulation of a mechatronic system including both mechanical and electrical parts requires a different strategy for the investigation of its robustness. Differences mainly results from interactions between the mechanical and the electrical part of the mechatronic system. Furthermore, a comfort mechatronic system in the automotive industry is designed customer-oriented. Subsequently, the behavior of its movement and the respective robustness has to be considered too. This paper presents an approach to evaluate robustness of mechatronic comfort systems. Additionally, the approach is applied to sliding doors of vans to prove the practicability to industrial problems.
