“…The dry clutch model includes nonlinear representations of the cushion spring (k cs Þ and diaphragm spring (k ds Þ stiffnesses [34]. The former corresponds to the clutch disc normal compression and reaction between the pressure plate and flywheel, and the latter describes the connection of the pressure plate with the pressure plate cover.…”

Determining the root causes of Noise, Vibration and Harshness (NVH) phenomena in modern automotive drivetrains is a task of critical importance. This research investigates the stability of dry clutch systems vibrational behaviour during engagement. A fully coupled dry clutch numerical model including the influence of friction is presented and validated using vehicle measurements. The clutch component frictional properties are measured using parts that exhibit aggressive NVH behaviour using representative tribometric experiments. The validated numerical tool highlights the occurrence of instabilities which are caused by modal couplings, particularly between the input shaft bending and clutch disc radial motions. Such a validated transient dynamics model of a dry clutch system has not hitherto been presented in the open literature.

“…where the coefficients describing the spring force are a ds =2905:56656, b ds ¼ 499:77521,c ds =3:04294 An example showing the nonlinearity of the diaphragm spring can be also found in [34]. The maximum compression of the cushion spring is considered to be at 0.6 mm, and at this point the clutch is described as closed.…”
