“…Regarding the stiffness of the components of the powertrain, all of them have been measured with relatively high precision, except for the torsional stiffness of the tires. As shown in the work of Drexl (1999), this parameter influences a mode whose eigenfrequency is below the eigenfrequency related to rattle noise. Apart from being below the idle speed of the vehicle, this mode is usually very damped and hence not very influent for this analysis.…”

“…This happens because the disks used for Run 1 and 2 have minimum friction torque, and hence system amplifications are able to reach high amplitudes. It is shown in the work of Steinel (2000) and Drexl (1999) that, in most cases, linear models of powertrain have a mode which has the highest amplitude of vibration on the gearbox and is highly influenced by the energy dissipation capability of the clutch disk. Therefore, this amplification was expected to occur.…”

“…It will attain to its most basic principles and characteristic curves to give basic technical knowledge necessary to understand the terminology on the literature review (Chapter 3) and to provide the physical association for the models on this thesis. References for a deeper research are Micknass (1993), Drexl (1999), and Shaver and Shaver (1997).…”
