“…Investigations regarding the influence of transient oscillations on human perception have come into focus in the past decade. For instance, Knauer [14] achieved fundamental insights into the masking effect of single obstacle excitations, which are applied in further research [15], [16]. The major restrictions on the scope of the experiments of Knauer were the frequency range limitation (0 Hz ≤ 𝑓 ≤ 40 Hz) and the missing option to independently control specific contact points between vehicle and human.…”

This paper presents the replication of accelerations in a vehicle excited from single obstacle crossings. The accelerations should be replicated at multiple comfort-relevant excitation points in a comfort-simulator. For the vertical accelerations at the seat rails and the foot rests, research on the positions and the number of shakers is conducted. The implementation of an electrodynamic shaker for each controlled measurement point turns out to be mandatory. By positioning them at the left and right seat rails, errors can be minimized due to similarities in the transmission behavior. The longitudinal excitations of the seat back by means of shakers are performed very precisely. The direct coupling by a construction on the headrest allows fast exchange of the vehicle seats. The combination of all acceleration replications simultaneously can be performed satisfactorily comparing them with in-vehicle field measurements. The noise-based excitation signal for system identification turns out to be a significant parameter.
