In order to achieve the dynamic simulation of vehicle clutch, the paper calculated the dynamic parameters of the locking and sliding process of vehicle clutch and established a Matlab/Simulink simulation model which can describe the revolution state of vehicle clutch. Also, it analyzed the dynamic behavior of clutch locking and sliding process. The research illustrates that the simulation model can correctly describe the dynamics of moving vehicle with combining and separating process of the clutch, and the dynamic simulation analysis reflects the alternation of clutch locking and slipping process more intuitively than the static model. Moreover, the method provides a reference for the dynamic control and integral optimization design of automatic clutch.
