Non-smooth multibody systems are influenced significantly by the states of all unilateral contacts. Discontinuities of the state variables and their derivatives as well as the structural variance cause severe problems in the numerical integration. There are two established solution methods. Event-driven methods determine the solution trajectories very accurately, time-stepping methods are more robust but are outnumbered concerning the efficiency due to their low numerical order. In this thesis a coupling approach of both methods is examined. The main focus lies on the strategy to switch between the two modes and the differences caused by different kinematic levels. Academic examples are used to compare these types concerning calculation time, robustness and accuracy.
