For the vibration problem of dual clutch power transmission system

the models of the dual clutch power transmission system dynamics and the hydraulic control system are established

the control of the transient change of power transmission system in engine and clutch is carried out

the vibration of engine and clutch

the stability of hydraulic control system are studied.The research results show that when the engine transmission power can produce vibration and instantaneous velocity impact.Through the double clutch

the output torque is stable

in inertial stage

clutch fluctuates significantly faster than the final torque oscillation stage

the higher control precision of the hydraulic control system

the power transmission system vibration is smaller.
