摘要
<div class="section abstract"><div class="htmlview paragraph">The functional extension of vibration reduction in continuous slip operation in modern wet-running clutch systems under dynamic excitation is being investigated by the authors. Therefore, a mixed virtual-physical validation environment has been developed using the IPEK X-in-the-Loop Framework and will be presented as part of this contribution. Thus, the validation environment enables the consideration of interactions with the residual systems, especially the residual drive train.</div><div class="htmlview paragraph">In this contribution, the validation environment is used to investigate whether and how an attribute variation in the subsystem, respectively the tribological system, can provide improved vibration reduction without increased power dissipation due to damping but other reducing mechanisms favored. The results show significant differences in vibration reduction behavior whereas the power losses are almost the same between the investigated tribological system. A main conclusion derived is: with an aimed design of the tribological system it is possible to favor other reducing effects beside damping and therefore favor a more efficient vibration reduction for the same dynamic slip operation.</div><div class="htmlview paragraph">The knowledge gained allows the clutch system to be designed specifically for functional extension, thus improving the trade-off between comfort and efficiency. Finally using the clutch system in hybrid electric vehicles as a mechatronic dynamic actuator enables weight- and space-optimized drive train development, which can eventually also improve efficiency, range and comfort behavior in electrified vehicles with gearboxes and provide a basis for the development of corresponding control strategies.</div></div>
