Keywords: multi-body simulation, helicopter, ground resonance

This work investigates the identification and impact of the helicopter ground resonance with the multi-body simulation code. Therefore, a model of rotor with rigid blades and a detailed model of a landing gear were integrated. The simulation results indicate a correct prediction of the occurrence of large vibrations and instabilities.
