Self-Eexcited Full-Vehicle Oscillations

In this paper, self-excited full-vehicle oscillations - in this context referred to as "Power-Hop" - and two appropriate remedies to reduce or prevent these oscillations are described. The results of full-vehicle measurements, as well as the development of a specially designed test rig, examinations and predictions of the MBS full-vehicle model are presented. By using the simulation model, the effectiveness of a specifically modified advanced driver assistance system, which should reduce the oscillations, is discussed. Furthermore, to avoid energy input into this vibratory system, the use and effectiveness of magnetorheological drivetrain mounts are presented.
