Non-linear multi-body dynamic analysis for the study of clutch torsional vibrations (judder)

摘要

This paper presents an investigation of the torsional vibration mode of the vehicular clutch system, referred to as judder. This phenomenon takes place during the clutch engagement process on light trucks with Diesel engines. A nonlinear multi-body dynamic model of the clutch mechanism is presented in order to study the effect of various clutch systems and driveline components on its vibration performance. The parameters include geometrical physical. inertial and force data of the clutch system of vehicles. The paper demonstrates that propensity to judder is related to the various friction lining materials' characteristics. (C) 2001 Published by Elsevier Science Inc. All rights reserved. References: 19
