Abstract
The clutch is slid for a short time at the engaging the gear of a manual gear car. The self-excited vibration might be generated at this time, and this is called clutch judder. The simulation model of clutch judder is studied here to clarify the relation between the clutch characteristic and clutch judder. First, the validity of the model is examined compared with a past analytical model. It is confirmed that the stability area and the frequency response of the simulation model are corresponding to an analytical model. The simulation result by this model is the following. (1) When clutch judder is generated, the clutch engaging time becomes long. (2) Sensitivity for generating clutch judder is different on a relative speed. A negative inclination of the μ-V characteristic of a high relative speed shows high sensitivity, and the possibility to generate clutch judder is increased.
