【 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, Simulate the variation of oil pressure in the inlet of clutch cylinder under different duty cycles. The fluctuation of the oil pressure at the inlet of the clutch hydraulic cylinder was simulated with different duty ratio reduction modes of the shift solenoid valve. Find a way that the duty cycle of oil pressure fluctuation decreased smallest.
