【 摘 要 】

The dynamic model of the hydraulic control system of the shift clutch is established through the flow equation of the valve port, the flow continuity equation and the balance equation of the valve core force, the piston motion of clutch cylinder is divided into three stages. And simulate the dynamic curves of the hydraulic pressure of the hydraulic inlet of the hydraulic cylinder during different stages.
