Design of the Power Unit in the Hydraulic Hybrid Vehicle

Abstract:

In order to reduce the energy consumption and the hydraulic noise, the paper modifies the hydraulic pump/motor and designs a novel high-speed filling valve for the system, which is normally open and large-diameter. The modified pump/motor and the valve constitute the power unit. In the ANSYS/FLUENT the paper simulates numerically the flow field in the high-speed filling valve. By the use of ANSYS/LS-DYNA the paper analyzes the impact stress of the valve core. According to the simulation results, the power unit is optimized. Tests show that the noise decreases significantly in the vehicle utilizing the valve.
