A new “E-E-K” (bionic) noise was generated during clutch engagement. By testing the vehicles with the EEK noise, the key parts for EEK noise and the motion modes were pointed out. The module of clutch engagement process was built. The stability of the system was analyzed based on the theory of Hurwitz. Then the multi-body dynamic model of the clutch system was built, and the corresponding EEK noise-vibration model system was created. A system vibration mode corresponding with EEK noise was established in the model, which simulated and reproduced the noise and vibration mechanism of the vehicle testing. All these verified the consistency between vehicle testing and model. Based on the multi-body dynamic simulation, the key component for EEK noise had been clarified, and the further research direction of EEK noise was pointed out.
