“…In the long term, the flexibility allows the combination with a driving simulator based on a hexapod system with extensive visualization. The use of a whole vehicle cabin adds visual and haptic influences, which are important for the overall perception of comfort [18]. The evaluation of the recorded signal data set and generation of the drive signals are shown in Fig.…”

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.

“…The use of a whole vehicle cabin adds visual and haptic influences, which are important for the overall perception of comfort. 20 The evaluation of the recorded signal data set and generation of the excitation signals is shown in Figure 1(c). The reduction of iteration effort and the periods, in which the test rig is not available for other tasks, is an essential attribute of the algorithm selection in this context.…”

This paper presents a method for replicating transient signals induced in a passenger car by single-obstacle crossings. These replicated signals should be used in a ride comfort simulator. By using feedforward-inverse-model-control with direct identification of the inverse transfer function, time-consuming iterations of conventional time waveform replication methods are eliminated. The quality of the system identification for approximating the inverse transfer function is significantly increased by decomposing the frequency band and the complexity is considerably reduced. The use of nonlinear block-oriented models significantly decreases the replication errors in frequency bands with high nonlinearity influence.
