Abstract:
Methodology to determine the clutch facing sensitivity regarding judder in the vehicle. Vehicle “Judder” is identified as low frequency and high amplitude vibrations that, depending on their intensity, can cause uncomfortable driving. Today the judder test is performed in the sensitive car concerning judder, however it takes long time due to the need of assembling the complete clutch set (disc, clutch cover, flywheel) for each test. So the aim of this work is to develop a methodology for classification of facing sensitivity regarding judder, however in subscale bench test, because the idea is not only to reduce test time but also to speed-up the facing material development. The preliminary results are very promising due to a good correlation between subscale tests and the vehicle.
