Control System Analysis of Hydrodynamic Retarder of Heavy Truck

In order to meet working requirements, the control system of hydrodynamic retarder of heavy truck should have the capability of rapid response and large flow. Based on the demands as above, a control system of hydrodynamic retarder was designed and simulated to obtain the dynamic characteristics of the control valve of oil-charge and oil-discharge. Finally, the time of oil-charge and oil-discharge of hydrodynamic retarder was computed and the results showed that the control system could meet the working requirements.
