Torsional vibration of multi-plate clutches analysed with hybrid method

Multi-plate clutches for automotive drivetrains have the following advantagesif compared to conventional single plate clutches. On the other hand, they require more space in axial direction for installation, whereby the number of friction-and steel-plates influences the transmittable torque behaviour. As it comes to friction in guide-ways, axial forces are reduced from one plate to another, which lowers the total torque transmission potential and influences the dynamic behaviour. This leads to different torsional vibration signatures under typical operating conditions and to special requirements on the applied analysis methods. In this context, the paper introduces a new approach of a hybrid adaptive analysis method of vibrations produced in non-stationary processes with the target to support evaluation of the operation and to improve control quality in different applications.
