Experimental Study of Reduction Methods for Clutch Pedal Vibration and Drive Train Rattling Noise from Clutch System

When a clutch pedal is operated, the clutch pedal vibration and interior noise are mostly affected by the dynamic characteristics of the clutch cover assembly. We achieved a high correlation between vehicle test data and results using this method when exciting not only clutch system but also the engine system. Finally, we developed an excitation method to evaluate the dynamic characteristics of the clutch cover assembly.
