A new hydraulic system in AT was designed. The parameters of every valve was designed by theoretical calculation. The dynamic simulation model of hydraulic system of AT was established by ITI-SimulationX. Simulation results and theoretical design results were compared to confirm the simulation model. Every valve-s dynamic characteristic in hydraulic system was simulated. The simulation results of pressure and flow of system pressure valve, shifting manipulations, torque converter and lubrication system were analyzed. The dynamic simulation method would be very helpful during the course of designing and analyzing the performance of system pressure valve and further optimization design. The theoretical design method and dynamic simulation model will be feasible for the real industrial applications. The research results can be used in design and optimization of hydraulic system.
